The Château de Luc was built in the 12th century on a previous Celtic site. The castle, as a strategic point between the two provinces of Gévaudan and Vivarais, guarded a link to the south of France of the Auvergne frequently used by pilgrims of Saint Gilles, also known as the Regordane Way, on which it was a toll-gate.
For the first 100 years or so of its existence it was the home of the Luc family. In the 13th century it became the property of other regional seigneurs. During the Hundred Years' War it withstood a number of sieges. During the 16th century Wars of Religion the state of Gévaudan garrisoned the castle. Around 1630 the castle was dismantled under orders of Richelieu. During the period surrounding the French Revolution it continued to fall apart from neglect.
It remains in ruins today and attracts hikers who re-trace Stevenson's route on the GR 70.
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.
