The temple of St. Giovanni (Saint John Sepulchre), known also as the Church of the Holy Sepulcher is a circular construction built towards the end of the 11th century by the Normans over the pre-existent church. It is one of the finest examples of Romanesque architecture in all Southern Italy. During the 12th century a new portal was opened, which today is the main entrance to the church. It has an architrave made from marble which is supported by two columns which rest on two lions made from marble as well.
This church was hold by the Order of Holy Sepulcher (Templars Knights) and subsequently by the Knights Hospitaller (also known as Knights of Rhodes, Knights of Malta, the Order of St John of Jerusalem).
The interior of the church is in the shape of a 'horse shoe' with eight columns in concentric circle within. This design is in memory of the Holy Sepulcher in Jerusalem.The original vaulted roof has been replaced by a new wood roof. On the walls there are fresco paintings from the 12th-15th centuries.
After the restorations necessary to bring the church back to use after it was almost destroyed by earth quakes, it was used as a museum from the years 1850 to 1955. It was a centre of cultural meetings attended by illustrious personalities such as Mahatma Gandhi and the famous Indian poet Rabindranath Tagore.

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.
