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.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
