The Protestant Church of Peace (Friedenskirche) is situated in the palace grounds of Sanssouci Park in Potsdam. The church was built according to the wishes and with the close involvement of the artistically gifted King Frederick William IV and designed by the court architect, Ludwig Persius. After Persius' death in 1845, the architect Friedrich August Stüler was charged with continuing his work. Building included work by Ferdinand von Arnim and Ludwig Ferdinand Hesse also. The church is located in the area covered by the UNESCO World Heritage Site Palaces and Parks of Potsdam and Berlin.
The cornerstone of the churchhouse was laid on April 14, 1845. The building was dedicated on September 24, 1848, though construction continued until 1854. The structure resembles a High Medieval Italian monastery. The Kaiser Friedrich Mausoleum was added to the north side between 1888 and 1890. The plans were drawn up by Julius Carl Raschdorff, who also designed the Berlin Cathedral from 1893 to 1905, in the style of the Baroque-influenced Italian High Renaissance. The 17th century Chapel of the Holy Tomb in Innichen, South Tyrol, Italy, serves as an archetype for the Mausoleum, which in turn was based on the chapel on Jerusalem's Calvary Hill. The mausoleum is a domed structure with an oval outline and an attached rectangular altar room. The inside contains a surrounding gallery and the domed roof, supported by two black columns, one on top of the other, which run around the edge. A golden mosaic on the inside of the roof shows alternating angels and palm trees.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
