The 'Vauban Fortress' of Foras was initially a strategic fortification established by Philip the Fair, circa 1300. The donjon was rebuilt in 1480-1490 by Jehan II de Brosse.
The creation of the Rochefort Dockyard in 1666 made it a centrepiece of the system for defending the approaches of the Charente, which is prohibited from entering. At the end of the 17th century, François Ferry, the engineer of King Louis XIV, transformed the old feudal residence into the fort. In 1689, Ferry reinforced the walls of the Donjon to set up a battery of 9 canons and a signaling point. In 1693 a lower circular battery was set up to control access to the river Charente. The donjon received a signal station from 1889 to World War II.
Today classified as a Historical Monument, the castle houses a museum of regional history. Free entrance or guided tour of the fortification and the underground parts of the keep at 2 p.m every day (except Monday) between June 1st and the third weekend of September.
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.
