The lordship of Sigournais has existed since at least 1050. It was then the property of Zacharie de Pouzauges, a vassal of the vicomtes de Thouars. In the 12th century, a priory dedicated to Saint-Saturnin was built within the walls of the castellum. Issues of cohabitation with the castle's inhabitants arose. Moreover, the current castle, built by Guyard de Sainte-Flayve, came into existence thanks to the relocation of the priory outside the enclosure.
Nothing remains visible from the ancient fortress of the 12th century; the foundations in the ground are located a bit further to the north, with the current castle covering a part of them.
The current castle, constructed under Guyard de Sainte-Flayve, dates from the late 15th century and has an almost pentagonal shape. This enclosure consists of curtain walls flanked by eight round towers and a large gatehouse tower. A dry moat carved into the limestone surrounds it all. The gatehouse tower serves as both a fortified entrance (gatehouse) and a main tower (keep). It consists of a large rectangular tower flanked by two round towers on each side, all crowned with a battlemented walkway on machicolations. The entrance corridor is divided into two entrances, one for carts and one for pedestrians. On the outside, a fixed bridge was extended by a cart bridge and a pedestrian drawbridge, side by side. Inside the gatehouse tower, there were two levels. On the first level, there was a guard room and a vestibule. Canon openings were arranged in the thickness of the wall. On the second level, accessible by the spiral staircase in the South flanking tower, there was a room serving both as a reception hall and as the lord's residence, separated by a wall was a chamber.
A large pentagonal courtyard was protected by walls and towers, crowned with crenellated battlements on machicolations, and probably served as a bailey (outer courtyard). Some buildings were attached to the ramparts, such as stables, kitchens, a bakery, forge, etc.
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.
