The St. Peter's Cathedral in Geneva is known as the adopted home church of John Calvin, one of the leaders of the Protestant Reformation. Inside the church is a wooden chair used by Calvin.
St. Peter's Cathedral was build between years 1160-1252, on the place where previously used to stand basilica from the 6th century. Cathedral was rebuilded several times, last reconstructions took place in 18th century. In 1397, the Chapelle des Macchabées was added to the original building and in 1752 the portico was added to the western facade. Interiors of the Cathedral were vastly demolished in 1535, when Geneva's residents accepted the Reformation and destroyed all the altars inside the cathedral, all the statues and most of the paintings in a rage. Luckily the Pulpit and some paintings at the tops of the pillars were preserved.
The cathedral has a old, spacious and rather plain interior, highlighted by shiny candle-like looking chandeliers, with beautiful shrine, several rows of benches and few chapels. Side aisles contains huge stone blocks - tombstones of church dignitaries from 15th and 16th centuries.
On the place of cathedral were recently found remains of basilica that was standing here previously, and mosaic paintings, walls, rooms and flooring from the buildings even several centuries older (dating back to the 4th century). All these historical findings are proving the existence of the city in the antiquity. There is a little museum made on the place of the Archaeological Site open for the public. You can see the artifacts and rooms found here, such as: The Roman Crypt, Monk's Cells, The Allobrogian Tomb and several Audio Shows portraying the history.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
