Bilstein castle is located on a spur which falls away steeply on three sides so that the castle's defences only needed to be oriented towards the hill to the northeast. The appearance of the castle is thus dominated by its two round towers, each with a diameter of about eight metres: the Chapel Tower in the northwest and the Hohnekamp Tower in the southeast. The towers are connected by a tunnel under the castle courtyard, above ground is a 20th century archway.
The castle was built between 1202-1225. The Electorate of Cologne conquered it after a siege in 1445. Later it has been used for administrative purposes.
The northwestern wing of the main ward and the central block in the southwest are historical structures. By contrast, the wing in the southeast was built in 1978 to expand the hostel. On the valley side of the central block is a portal terrace (Söller) on which a prominent lime tree is growing.
Today a brick bridge spans the moat between the inner and outer baileys. The moat has been partly filled-in and is about 15 metres wide. The outer bailey comprises three buildings, which are referred to as the gatehouse, timber-framed house and festival hall.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
