The Church of the Pantocrator of Patras is a Greek Orthodox basilica in the east side of the city. The current church was built in the mid nineteenth century, shortly after Greece's independence from the Ottoman Empire, and it is dedicated to Christ Pantocrator, or Christ the Ruler of All. The church is noted for its lead-covered domes and is considered to be a landmark of the upper town of Patras.
The site on which the current temple stands built has been sacred since ancient times. The temple of Olympian Zeus was destroyed during the early years following the Roman Empire's Christianisation; on its ruins a new religious building was erected, a church dedicated to Christ Pantocrator around the year 900 AD. During the Venetian rule of Patras in the fifteen century it was converted into a Catholic church and re-dedicated to Saint Mark. Much later, after Patras fell to the Ottoman Turks, it was converted into a mosque.
At the beginning of the Greek War of Independence in 1821, it was said that thet first bullets that fell in Patras against the Ottomans were made with lead taken from the dome of the mosque. Seven years into the war in 1828 the mosque was put to use as a hospital for the French Army Commander-in-Chief Maison.
After Greece achieved independence from the Ottoman Empire, the original church/mosque building was demolished and the current, larger church was built. The erection of the current Pantocrator church as it is today, is calculated (based on existing data) to have taken place around the years 1835–1840, during the early years of Greece's independence. The old mosque's minaret, which once stood to the southern side of the building, was demolished.
Ever since the current church's construction was completed various additions and repairs have been made from time to time, the most noteworhty of those being the copper-covering of all the larger and the smaller domes of the roof in 1951.
One of the most imposing buildings in the city of Patras, Pantocrator Church has attracted the attention of many foreign travellers and pilgrims, who have made several references to the church in their documents, as well as many depictions of it in engravings and drawings of the 19th century.
The first church building from the tenth century was a smaller one, built according to the of design trends the era. After its conversion into a mosque, a thin, pencil-like minaret was added to the south corner of the former church.
This Byzantine-inspired church is a three-aisled basilica covered with domes, with the central, larger dome resting on four spherical triangles, while in the east and west there is a quadrisphere for bearing loads. It was built to some extent to mimic the design of the Hagia Sophia in the imperial capital Constantinople (now Istanbul), with the external vaults facing north and south, which are rare to find in many Orthodox churches in Greece.

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.
