History
Navahrudak Castle is a fortified site in Belarus, located at Navahrudak, that developed under Lithuanian rule from the eleventh century into the seventeenth century. It began on the site of an older settlement on Castle Hill and became an early political and residential center of the Grand Duchy of Lithuania, a medieval and early-modern state whose rulers controlled much of present-day Belarus, Lithuania, and neighboring regions.
Early stronghold and Lithuanian rule
The earliest fortress consisted of a citadel on the summit and an adjacent residential area known as the Small Castle. From the beginning of the eleventh century to the middle of the thirteenth century, the citadel was defended by earthen ramparts and wooden structures. These defenses were rebuilt or altered at least five times. During the second half of the thirteenth century, strong oak fortifications with double walls replaced much of the earlier arrangement.
One tradition attributes the castle’s foundation to Mindovg, also known as Mindaugas, the thirteenth-century ruler who became the first and only crowned king of Lithuania. Another historical interpretation attributes its foundation after 1241 to the Lithuanian prince Edyvil. Mindovg established his capital at Navahrudak, was baptized there, and was crowned king of Lithuania in 1253. The settlement consequently became one of the early political centers of the Lithuanian state.
A first stone tower was erected under Mindovg during the second half of the thirteenth century, within the earlier timber defenses. It later formed the basis of the Shield Tower. The fortress resisted attacks by Galician-Volhynian and Tatar forces in 1274, as well as repeated Teutonic assaults in 1314, 1391, and 1394.
Sieges and political importance
The 1314 attack was led by Henry von Plotzke. After the first assault failed, the Teutonic forces camped around the fortress and tried again. The defenders drove them back with spears, bows, crossbows, and large wooden logs. A cavalry force led by David of Grodno, the castellan responsible for the fortress, attacked the crusaders’ baggage train, seized supplies and 1,500 warhorses, and helped force the siege to end.
In 1391, the Teutonic Grand Master Konrad von Wallenrode withdrew after his heavily armoured troops were unable to climb the steep hill. Another Teutonic army, commanded by Grand Master Konrad von Jungingen and Marshal Werner von Tettingen, also failed to capture Navahrudak in 1394.
The castle’s political role extended beyond warfare. It served as a residence of the grand dukes of the Grand Duchy of Lithuania and as a center of the town’s political life. In 1422, it hosted the wedding of the sixty-year-old Wladyslaw II Jagiello, king of Poland and grand duke of Lithuania, and the seventeen-year-old Sophia of Halshany. Their two sons made Sophia the ancestral figure of the Jagiellonian dynasty, the ruling house that produced kings of Poland and grand dukes of Lithuania.
Noble assemblies of the Navahrudak district met at the castle. From 1581 to 1775, sessions of the Tribunal of the Grand Duchy of Lithuania were held there or in its church. The Tribunal was the state’s highest appellate court, giving the fortress a judicial and administrative function as well as a military one. From 1638, the Shield Tower was adapted to hold archival books.
Later attacks and destruction
Tatar forces led by Biti Giray attacked Navahrudak in 1505 with the support of Turkish janissaries, infantry trained in siege warfare. The defenders, led by the voivode V. Gashtold and the town mayor Maskiewicz, repelled the assault. Further Tatar attacks in 1506 also failed. A Russian assault in 1535 was unsuccessful, but the castle gradually lost strategic importance as the state frontier moved farther away. Reduced royal interest contributed to the fortress’s deterioration during the sixteenth century.
The war between the Polish-Lithuanian Commonwealth and Russia from 1654 to 1667 brought severe damage. Cossacks commanded by Ivan Zolotarenko captured Navahrudak in 1655 and badly damaged both the town and the castle. In 1660, forces under Ivan Khovansky occupied the partially restored fortress after its unpaid garrison surrendered without a fight. The war destroyed several towers and connecting walls.
Swedish forces demolished the remaining fortifications in 1706 during the Great Northern War, the conflict in which Sweden fought Russia and its allies for control of territories around the Baltic Sea. In 1802, the Lithuanian governor-general Bennigsen ordered the surviving walls dismantled for street paving. During the late nineteenth century, dumping covered much of the ruins with a layer of refuse about two metres thick.
Archaeology and conservation
By the beginning of the twentieth century, only the Watchtower, Shield Tower, and Kostelnaya Tower remained substantially above ground. Part of the Shield Tower collapsed in 1906, while the Kostelnaya Tower suffered a major collapse in 1914. The First World War brought down the southern wall of the Shield Tower.
The ruins received state protection in 1921. Polish archaeologists undertook conservation between 1922 and 1930 and rebuilt collapsed sections of the Kostelnaya Tower. Archaeological work resumed in 1956, and major architectural and archaeological studies from 1969 to 1973 clarified the castle’s successive construction phases. Excavations in 1924, 1930, and 2011 exposed additional tower foundations, a barbican, a vaulted passage, and sections of wall.
Large-scale conservation and restoration began in 2012 under the state Castles of Belarus program. The work included stabilizing the slopes, improving drainage, and conserving surviving structures. An organized drainage system was completed in 2021, while the slope between the Kostelnaya and Entrance Towers was strengthened. The fifth conservation stage, completed in 2024, exposed and conserved the circuit of walls around Castle Hill and brought the buried remains of the Entrance, Watch, and Posadskaya Towers to the surface. Navahrudak Castle is a protected historical and cultural property of Belarus under state code 411G000404 and is recognized as an important example of medieval defensive and Belarusian Gothic architecture.
Remains
Navahrudak Castle occupies Castle Hill, a high partly artificial hill about 323 metres above sea level and surrounded by a deep moat. Its defenses were arranged in two polygonal belts: an upper enclosure on the summit and a lower line running along the slopes. The main Castle Hill was paired with the lower Small Castle, which contained residential areas. The site formed part of the Lida, Kreva, Medininkai, and Trakai defensive line.
Castle Hill defenses
The northern and northwestern approaches were protected by a large earthwork and a moat up to 30 metres wide and 4 metres deep. Another earthwork reached about 5 metres in height. Steep slopes extended for roughly 50 metres, with gradients reaching 60 degrees. Timber defenses remained in part of the northwestern sector until the end of the fifteenth century, while the later fortress combined these earlier earthworks with stone and brick towers and walls.
First Stone Tower
The First Stone Tower was a nearly square thirteenth-century structure measuring about 12 by 12 metres. It stood in the northern part of the fortress near the entrance, projected slightly beyond the earthen rampart, and helped close the defensive circuit. Its foundation rose about 3.5 metres. The lowest stones reached up to one metre in size, and surviving masonry rises to four metres in places.
Local roughly dressed stone was set in lime mortar, with carefully fitted medium-sized stones forming the walls. Fine gravel filled the joints, and some sections contained brick fragments sealed with lime. The tower’s construction has been attributed to local craftsmen. The fourteenth-century Shield Tower was built over its remains.
Shield Tower
The Shield Tower, also called the Central Tower, was built of brick in the fourteenth century on the foundations of the First Stone Tower. It had an approximately square plan, measuring 11.4 by 12.4 metres, and rose five storeys to about 25 metres. Beam floors divided the interior. The walls were about 2.75 metres thick on the first floor and 2.6 metres on the second, narrowing upward in the form of a truncated four-sided prism.
Loopholes, narrow openings for projecting weapons, pierced both the exterior and interior walls, and many ended in semicircular arches. A staircase built into the southern wall led from the southwestern corner to the upper levels. Wooden stairs may also have supported everyday movement between floors. A small eastern oriel at fourth-floor level contained a bell used to warn the population of danger. The tower originally had a slab roof, later replaced by stone shingles. Today its ruins form one of the principal surviving parts of the castle.
Kostelnaya Tower and connecting walls
Kostelnaya Tower stood east of the Shield Tower above a steep slope. Its square base measured about 9 by 9 metres, with foundations three metres deep made from large rough stones. The lower four metres were built of stone, while the upper section used large bricks. Its walls were about 2.15 metres thick at the base and became narrower higher up.
Groups of four loopholes were arranged every three courses in the tower walls. A 30-metre wall, about two metres thick, connected Kostelnaya Tower with the Shield Tower. Another stone wall, about 80 metres long, ran eastward along the slope toward the Small Tower and was later strengthened with buttresses. The Kostelnaya Tower has been stabilized with a spatial metal framework and additional handmade restoration brickwork. Drainage works and approximately 100 bored-injection piles have reinforced the adjacent slope.
Lower defensive belt
Small Tower
The Small Tower, also known as the Small Gate or Entrance Tower, had a rectangular plan measuring about 8 by 10 metres. Its walls were two metres thick. Oak entrance gates fitted into sockets in the masonry, and the opening measured 1.6 metres wide by three metres high. Brick steps connected it with the street.
The tower probably had three storeys. On the courtyard side, a fighting gallery rested on projecting wooden beams and was reached by a wooden ladder. A narrow opening about 94 centimetres wide led from the gallery to the second storey. The tower was fully excavated in the late 1920s, after which its walls were partially reconstructed.
Posadskaya Tower
Posadskaya Tower stood at the western end of the Small Tower’s defenses. Its upper structure was destroyed down to the foundations, which formed a square about 7.7 by 7.7 metres. The walls were 2.6 metres thick. A passage 1.5 metres wide led into the tower, and a nearby gun loophole measured up to one metre wide and 1.3 metres high.
A 70-metre wall connected with Posadskaya Tower. At about 2.6 metres thick, it was the thickest stone wall in this sector. Timber fortifications continued from it toward the northwestern edge of the hill, while earthworks and the moat protected the lower defenses. Excavations have exposed the foundations of Posadskaya Tower and sections of the surrounding walls.
Well Tower
The Well Tower was built in the early fifteenth century over a spring on the eastern slope. It supplied water during a prolonged siege because the summit had no well. The tower measured about 8 by 8 metres and had foundations 2.5 metres deep, constructed from large rough stone blocks set in lime mortar.
A stone wall connected the tower with the castle and contained a concealed passage to the spring. The passage ran beneath a vaulted covering through walls about two metres thick and was no more than one metre wide. Large square bricks, about 35 centimetres thick, were used on the tower’s upper surfaces. Their arrangement followed a Baltic masonry pattern, with two bricks laid lengthwise followed by one laid across them.
Watchtower
The Watchtower was built in the northwestern part of the fortress in the late fifteenth or early sixteenth century. Its square foundation measured 14 by 14 metres and rested on a four-metre stone-and-brick foundation laid in bands. Low-level loopholes were designed for gunfire. The foundations indicate that the tower was at least as high as the Shield Tower and possibly higher.
A 51-metre defensive wall, two metres thick, connected the Watchtower with the Shield Tower. This wall completed the circuit of stone fortifications and replaced the remaining timber enclosure. The buried foundations of the Watchtower have been brought to the surface and conserved.
City Gate Tower
The City or Settlement Gate Tower was built on the southeastern slope in the early sixteenth century to strengthen the approach from the expanding town. It formed the center of the lower defensive belt and was connected to the Well Tower and Small Gate by walls. Its arrangement required attackers to pass through two gates while exposed to defensive fire. Its original dimensions are unknown.
Small Castle and citadel buildings
Small Castle tower
The Small Castle had a separate second defensive line around its residential area. On its western side stood a rectangular tower measuring about 12.3 by 10.9 metres, with walls 2.6 metres thick. Built of local stone and brick in the late thirteenth or first half of the fourteenth century, it was reconstructed several times. It was later replaced by an eight-sided brick tower and finally destroyed in the middle of the seventeenth century. Its materials were subsequently reused in a windmill.
Church and princely palace
A stone church stood inside the citadel from at least the fourteenth or fifteenth century. It began as a single-apse building without columns. Four cruciform columns were later inserted beneath the dome, and further extensions gave the building the appearance of a Baroque church with one bell tower. One tradition identifies it as the Church of the Assumption of the Blessed Virgin Mary, while another tentative identification names it as the Church of Saint Michael.
In the early eighteenth century, the church was used to store books belonging to the district and Tribunal courts. A two-storey stone princely palace stood to its north and survived until the middle of the seventeenth century.
Conserved archaeological remains
Archaeological investigations have revealed the foundations of the Entrance, Watch, and Posadskaya Towers, along with sections of the surrounding walls that had been buried. The exposed ancient masonry was raised by about 1.5 metres using new stone and brick. The additions were distinguished from the surviving fabric, producing a partially closed circuit while preserving the archaeological remains as separate layers of the site’s history.
The conserved remains include the ruins of the Shield and Kostelnaya Towers and exposed foundations of other towers and walls. Together, these structures show the development of Navahrudak’s defenses from earthen and timber ramparts into upper and lower stone-and-brick fortification belts.
