The fortified town of Rello still maintains the original defensive walls and castle that were used as protection against civilisations that came from the south following the Douro River. It is the best-preserved walled enclosure in the province.
You can go inside through either one of the two gates located on the sides of the castle. The castle is protected by a fortified enclosure with circular and quadrangular towers that have elbow openings. The upper part of the towers are crowned with 15th-century machicolations and you can still see some remains of the keep, a water pool and a wall of the gate that separated the castle from the rest of the town.
In the outer enclosure, there are still gunboats in the lower section that were used for artillery.
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.
