Palencia Cathedral was built from 1172 to 1504 stands over a low vaulted Visigothic crypt (the Crypt of San Antolín). It is a large Gothic building, popularly dubbed as 'The unknown beauty' because not as well known as other Spanish cathedrals, though, it is a valuable building which has in its interior a large number of works of art of great value.
Its more than 130 metres long, 42 metres high and 50 metres wide at the centre, making it one of the largest cathedrals in Spain and Europe.
Its exterior solid, simple and austere does not reflect the grandeur of its interior, with more than twenty chapels of great artistic and historical interest. The most recognizable on the outside, is the tower, slim but a little rough, considering your Gothic style. Recent studies and excavations show that it was a military tower, and after serving this function were added to their pinnacles and cattail as the sole decoration.
The Cathedral's museum contains a number of important works of art, including a retablo of twelve panels by Juan de Flandes, court painter to Queen Isabella I of Castile and El Greco's St. Sebastian' (1576–79).
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.
