History
Rieneck Castle is a medieval hill castle in Rieneck, Germany, built by Ludwig I, Count of Loon and Rieneck, around 1150 as the castrum Rinecke. Constructed on the northeastern boundary of the County of Rieneck, it protected the family’s territory against the neighboring lordships of Mainz, Würzburg, and Fulda.
Foundation and medieval expansion
The castle’s position above the Sinn valley gave the Counts of Rieneck a fortified base on their frontier. Its presence also encouraged settlement below the hill. By the beginning of the thirteenth century, the settlement was being described as a town, reflecting the castle’s role in the growth of Rieneck.
Rieneck Castle entered wider dynastic politics in 1188, when it was named in a treaty between Emperor Frederick I Barbarossa and King Alfonso VIII of Castile. The agreement included the castle among 29 Staufen possessions intended as part of the dowry for the proposed marriage of Frederick’s son Conrad to Alfonso’s daughter Berengaria. The marriage did not take place, but the treaty shows that Rieneck was considered part of a significant princely inheritance.
Around 1200, the fortifications were enlarged and strengthened. The expansion included the construction of a second fortified tower and a courtyard chapel, as well as measures intended to accommodate a larger garrison. The site’s defensive importance was also connected with the Birkenhainer Straße, the region’s most important medieval road, which the castle controlled.
Shared lordship and decline as a residence
The castle and town later passed into joint rule after the extinction of a Rieneck line. This change is associated either with the end of the Rieneck-Rothenfels line in 1333 or with the death of Count Philipp III of Rieneck in 1559. In the resulting condominium, a territory governed jointly by different authorities, Kurmainz held three-quarters and Hanau or Hanau-Münzenberg held one-quarter.
The settlement reached in 1559 followed a dispute over Philipp III’s planned inheritance by Count Philipp III of Hanau-Münzenberg. A formal legal error prevented that inheritance from taking effect, and the dispute was resolved through shared lordship. Because the castle had passed beyond the direct control of the Counts of Rieneck, it no longer served as a suitable comital residence. The counts moved to Lohr am Main.
Rieneck retained a strategic function through its position above the Birkenhainer Straße, but that role was abandoned during the sixteenth century. The castle then increasingly fell into decay. Its later history was shaped by changes in territorial authority. Johann Hartwig, Count of Nostitz, bought the Mainz share in 1673 to gain the rank of an imperial count with a seat and vote in the Imperial Diet. The share passed to the Counts of Colloredo and Mansfeld in 1803.
Rieneck was mediatized in 1806, meaning that its formerly autonomous position within the Holy Roman Empire was incorporated into a larger state. It became part of the Principality of Aschaffenburg, then passed to the Grand Duchy of Frankfurt. After Napoleon’s defeat in 1815, it was incorporated into the Kingdom of Bavaria.
Restoration and changing uses
Around 1860, the Würzburg physician Franz von Rinecker purchased the castle because he believed he had demonstrated a close connection with the Rieneck comital family. He financed extensive restoration and alteration in the Gothic Revival, a nineteenth-century movement that reinterpreted medieval Gothic architecture. These works made the original medieval fabric difficult to distinguish from later additions in some parts of the complex.
The poet and writer Walter Bloem owned the castle during the 1920s. A major rebuilding in 1929 added further changes. Afterward, the complex served successively as a children’s holiday home, an SA sports school, a military hospital, a military prison, and a hospital. The SA, or Sturmabteilung, was a Nazi paramilitary organization active during the period of National Socialist rule in Germany.
Protestant scouting centre
In 1959, a legal association created for the German Christian Pathfinder Association leased the castle. It acquired the property in 1967. Following the merger of several Protestant scouting organizations, the association became the Bildungs- und Erholungswerk Burg Rieneck of the Verband Christlicher Pfadfinderinnen und Pfadfinder, commonly known as BEW.
Rieneck Castle is now owned and operated as one of the federal centres and international training and meeting centres of the Verband Christlicher Pfadfinderinnen und Pfadfinder, a German Protestant Christian scouting organization. Its activities include conferences, training courses, arts programmes, scouting activities, and instruction in pioneering and medieval crafts. The Hesse branch also holds its annual Federal Assembly at the castle.
Modern changes have added facilities to the historic complex. A hall building enlarged it in 1976, and the hall wing was generally renovated by May 2003, when an additional roof floor was created. From 2017 to 2019, an energy-efficiency project replaced oil heating with solar thermal energy, a heat pump, and pellet heating. The work also improved fire protection and enlarged the kitchen through an extension in the castle courtyard. The International Arts Workshop, a multi-day music and creative training course for scouts over 17, has been held annually around Easter and usually attracts about 100 participants.
Remains
Rieneck Castle stands on a small hill in the Sinn valley, overlooking the Sinn River in the Spessart hills. The surrounding terrain provided natural protection, so additional defensive construction was concentrated on one side. There, a defensive ditch was built and the approach was kept narrow to reduce the width of the attacking front. The medieval complex centred on a courtyard enclosed by defensive walls, with two principal fortified towers, the Thick Tower and the Thin Tower.
The original fortress
Thick Tower
The 19-metre-high Thick Tower has an irregular seven-sided plan, with one point directed toward the nearby hills. Its walls are between four and eight metres thick. This unusual form reduced the exposed front toward the direction from which an attack was most likely to come. The tower was a Bergfried, the principal fortified tower of a medieval German castle, intended mainly for defense and refuge rather than permanent residence.
The Thick Tower was occupied during wartime because its defensive purpose made it relatively uncomfortable for ordinary living. It originally had no entrance at ground level. Two higher entrances were reached by wooden outside stairs that could be removed quickly. The present ground-floor entrance dates from the nineteenth century.
Count’s Hall and women’s chamber
The entrance at the level of the second upper floor led into the Count’s Hall, the tower’s principal room. It contained a hearth, a washbasin, and a concealed toilet, making it unusually comfortable by contemporary standards. On the third floor, a separate entrance led to the women’s chamber, or Kemenate, a heated private room traditionally associated with the women’s quarters of a medieval noble household. During a siege, it provided the countess and her attendants with secure accommodation and could be warmed by the fireplace in the Count’s Hall.
Tower chapel
The third floor also contains the tower chapel. It is completely embedded within the tower’s outer wall, an arrangement described as unique on the European mainland. Fitting a chapel into the defensive structure presented a considerable construction challenge. Surviving stonework on the walls conveys the former elaborateness of its decoration.
Vaulted cellar
Half-timbered buildings once occupied the courtyard inside the defensive walls. They provided living quarters, storerooms, and stables. The substantially surviving element of this group is the vaulted cellar, also called the arched cellar, which preserves part of the domestic and service arrangements of the medieval complex.
Twelfth-century additions
Thin Tower
The 29-metre-high Thin Tower was built around 1200 when the fortifications were strengthened to protect a larger garrison. It has an octagonal plan and originally had neither windows nor a ground-level entrance. Its interior fittings have disappeared, while its exterior has been substantially altered. The sixth floor, known as the Eagle’s Nest, and the present roof were added during the twentieth century.
Courtyard chapel
A Romanesque courtyard chapel was built during the expansion of the fortifications. Romanesque architecture is characterized by heavy masonry, rounded arches, and solid wall construction. Only parts of the chapel’s portal survive in the gable wall.
Later fabric and present complex
Connection wing and figure slabs
The connection wing between the Thick Tower and the Thin Tower dates from the 1929 rebuilding. That work also inserted windows into the Thin Tower and gave its roof substantial dormer windows for the first time. Two figure slabs from around 1300 are set into the exterior facade. Their origin and meaning remain uncertain. They may have belonged originally to the castle, or they may have been installed there during the nineteenth century.
Modern buildings and grounds
The later hall building, kitchen extension, roof-floor additions, and fire-protection and energy improvements form part of the castle’s current built complex. The facilities provide 134 beds and several meeting rooms. A campsite for about 100 people has operated at the foot of the castle since 1998. A permanent sanitary building was added in 2003, followed by a permanently installed high-ropes course in 2006.
