The Caixa de Rotllan (meaning 'Roland's Tomb' in Catalan language) is a dolmen dating back to the Neolithic period, during the second half of 3rd millennium BC.
A legend holds that Roland lived in Vallespir and that, after his death at the Battle of Roncevaux Pass, his horse Veillantif carried Roland's corpse back to Vallespir and buried him under this dolmen. Dolmens are actually tombs, but they were erected many centuries before the legendary knight's adventures.
The Caixa de Rotllan is made of three upright stones making a H-shape, supporting a thick roofing stone and delimiting a rectangular, medium-sized chamber.
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.
