History
Šomoška Castle is a medieval fortress in Slovakia, built during the thirteenth century on a volcanic hill above the historic Slovak-Hungarian border. It probably originated with the Kacsics family, a powerful landholding dynasty that established several castles in Nógrád County. The fortress formed part of the wave of stone fortification that followed the Mongol invasion of 1241, when the devastation of the Kingdom of Hungary encouraged the construction of stronger defensive sites.
Foundation and royal administration
The initiative to establish the castle is sometimes associated with Illés of the Kacsics family. Its position between Fiľakovo and Salgótarján placed it in a highland zone with military and political importance. In the early fourteenth century, the fortress came under the control of Matúš Čák, also known as Matthew Csák, a Hungarian oligarch who controlled a large territory and resisted royal authority. His followers used castles in their territories to attack supporters of the Hungarian crown.
King Charles I restored royal authority and confiscated the Kacsics possession, granting it to his loyal supporter Tamás Szécsényi. The castle appeared in a royal record of 1323 as castrum Somoskw. Under the Szécsényi family, Šomoška became a regional center of social and political life. Financial difficulties later weakened the family’s position. Ladislaus Szécsényi pledged the castle to Mihály Országh in 1455, and in 1461 to Albert Lossonczy, the husband of his daughter Hedviga. The Szécsényi line ended in 1461, while the Lossonczy family acquired the castle in 1481.
Ottoman frontier warfare
The Ottoman conquest of Buda in 1541 brought the castle into a more dangerous military environment. After the nearby fortresses of Fülek and Salgó fell to Ottoman forces in 1554, Šomoška was surrounded by territory under Ottoman control. Its small garrison, consisting of 50 infantrymen, 40 hussars, and 10 artillerymen, resisted for roughly two decades. It also disrupted communications with Fülek, despite its limited strength.
In 1576, an Ottoman army led by the bey of Fülek captured Šomoška, and the garrison withdrew to Eger. A Hungarian royal army recovered the castle without a fight in 1593, following the defeat of Ottoman forces at Fülek. After the death of its owner Anna, the daughter of István Lossonczy, the fortress passed to the Forgách family.
Seventeenth-century conflicts
Šomoška changed hands during the uprisings against Habsburg rule. Forces associated with István Bocskay seized it in 1605, but it returned to the crown after the Peace of Vienna in 1606. Gabriel Bethlen’s troops occupied the castle in 1619, and the Peace of Nikolsburg ended that occupation. As an outer defensive position for Fülek, Šomoška was repaired and strengthened on the orders of the Hungarian Diet in 1608, in 1618 and 1619, and again in 1648. Its military usefulness remained restricted by a shortage of water.
The garrison surrendered to the forces of Ferenc II Rákóczi in 1703 during his major uprising against Habsburg rule. After the revolt was suppressed, the Forgách family lost the castle in 1709, and the king ordered its demolition. The tenant Ráday burned only part of the roof, but the fortress nevertheless ceased to have military importance. A lightning strike caused a further fire in 1826. The ruins were subsequently used largely as a source of building material by local inhabitants.
Border changes and conservation
After the First World War, the Treaty of Trianon placed the castle in Czechoslovakia, while the status of the nearby settlements Somoskő and Somoskőújfalu remained disputed. The two settlements returned to Hungary in 1924, but the castle and its basalt quarry remained in Czechoslovakia and later Slovakia. The site belonged briefly to Hungary between 1938 and 1945 under the First Vienna Award.
Partial restoration began in the 1970s. The work was later interrupted after Slovakia became an independent state, leaving the fortress only partly reconstructed. The surrounding area was declared the Šomoška National Nature Reserve in 1954 within the protected Cerová vrchovina landscape. The reserve safeguards volcanic landforms and diverse plant and animal communities. An ecological trail was established there in 1987, and a spring was captured on the initiative of Dr. Gabriel Krúdy.
Remains
Šomoška Castle occupies the restricted summit of a volcanic basalt hill at an elevation of about 490 metres. Its compact plan reflects the limited space available on the hilltop. The fortress was organized around a small triangular forecourt, the principal palace, and service or economic buildings. Basalt from the nearby formation was used throughout the complex for walls, paving, and stairs, giving the castle a material character unusual among Slovak castles.
Fortifications and towers
Outer defenses and artillery works
The defensive system developed as artillery became widespread during the fifteenth century. A southern horseshoe-shaped bastion, a western rounded or cylindrical bastion, and a northern barbican, a fortified outer defense protecting an entrance, enlarged the earlier arrangement. During the seventeenth-century uprisings, the residential quarters were expanded and double walls were added at the gate. A polygonal artillery bastion projecting toward the northeast probably represented the final major addition. Its connection with the main fortress remained incomplete or was not made.
Round towers and entrance
Three round towers formed part of the defensive system. The northern tower, protected by the barbican, served as the entrance. The western and southern towers functioned as bastions and contained loopholes for weapons. Many cut basalt columns have almost regular pentagonal or hexagonal cross-sections, while the walls, stairs, and paving also use stone taken from the nearby volcanic formation.
Palace and interior buildings
Gothic palace
Behind the fortification walls stood a small Gothic palace. Its surviving form belongs to a complex that was repeatedly altered during the castle’s military history and later affected by demolition and fire. Parts of the fortress were partially reconstructed or restored during the work begun in the 1970s, while other sections remain in a ruinous and partly rebuilt state.
Service buildings and defensive corridors
Two additional buildings occupied the northern and southern sides of the interior. Northern and southern defensive corridors protected these structures and linked them to the wider fortified arrangement. The restricted summit area required the buildings and defenses to be fitted closely together within the small hilltop complex.
Basalt formations and surrounding landscape
Basalt stone waterfall
Near the castle, the Šomoška basalt “stone waterfall” forms a block more than 10 metres high. Its surface resembles thin streams of flowing water because lava from an ancient volcano cooled slowly into columnar basalt. Columnar basalt develops when thick lava cools and contracts, producing regularly jointed polygonal columns. Medieval quarrying removed much of the visible basalt in the formation as builders searched for stone for the castle.
Stone sea
The adjacent “stone sea” formed through erosion and the downslope movement of rock during the last glacial period. It also contains fragments from the basalt waterfall and other stones transported during construction of the castle. The formation provides a natural habitat for reptiles and amphibians, including the Aesculapian snake, fire salamander, and green lizard.
Nature reserve
The ecological trail through the reserve is 1.6 kilometres long and has a vertical difference of 106 metres. It passes three artificial ponds built in the 1920s for fish breeding. Water reaches the ponds through a fissure in the basalt at a relatively constant rate of approximately 0.3 litres per second, and the slightly mineralized spring was captured in 1987 in association with Gabriel Krúdy.
Broad-leaved woodland dominates the reserve, with European beech, sessile oak, Turkey oak, and European hornbeam. Some trees are approximately 100 to 150 years old. The protected flower Lychnis coronaria also grows there, while nesting birds include the stock dove, collared flycatcher, and grey-headed woodpecker. A separate volcanic hill nearby contains Salgó Castle.
