The Rotunda of the Holy Cross is the oldest Romanesque rotunda in Prague. It was built in the 11th century. The first mention of the Rotunda of the Holy Cross is from 1365, but it was probably built already at the end of the 11th century. It is a small simple building with a rounded nave and an apse. A lantern at the cupola has a gilt cross, a crescent moon and an eight-pointed star at the top.
Rotunda of the Holy Cross was probably a private chapel belonging to some of the mansions in Prague Old Town. There used to be a parsonage nearby and a cemetery around.
Dominicans gained the rotunda in 1625. Emperor Joseph II. abolished the chapel in 1784, as well as many other churches, and it became a private storage. It was planned to demolish the rotunda in 1860 because of building a new house at the place, but it was finally saved.
There are remains of Gothic wall paintings from 14 th century inside. The most valuable Gothic fresco is the “Three Magi veneration”. There are also some remains of tombstones from 13 th century.
The legend about the origin of the rotunda says, that there used to be a lake at the place originally. A crucified girl, punished for her Christian belief, was thrown there with her cross. The cross reared up during a storm, which was regarded as a God´s sign. A large dozy cross was really found in the foundations of the rotunda, when it was restored.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
