The original Church of Saints Clement and Panteleimon is believed to have been built when Saint Clement arrived in Ohrid at the request of Boris I of Bulgaria and restored an old church. Sources say that Saint Clement was not satisfied with the size of the church and therefore built a new one over it and assigned Saint Panteleimon as its patron saint.
Saint Clement used his newly created church as a liturgical building and a place for teaching his disciples in Old Church Slavonic and Glagolitic alphabet. Clement was buried inside the church after his death in 916; his tomb still exists today.
In the 15th century, Ottoman Turks converted the church into a mosque but during the beginning of the 16th century allowed ruined monasteries and churches to be restored, therefore, so was Saint Clement's church. The church was again ruined during the end of the 16th century or the beginning of the 17th century and another mosque, called Imaret Mosque, was erected by the Ottomans. The Imaret Mosque was torn down in 2000 with the reason given that it was constructed over the remains of a church in the Plaošnik area and the former mosque was added to the damaged religious buildings list compiled by the Islamic Religious Community of Macedonia.
The church stands on a hill which is now known as Plaošnik overlooking Lake Ohrid. Clement built his church on a restored church and a Roman basilica of five parts (the remains of the basilicas can still be seen outside the church). Judging by the architectural style and design of the church, researchers say that Saint Clement intended for his building to be a literary school for disciples, thus it is believed to be the first and oldest discontinued university in Europe.
The exterior of the church contains a large number of finely detailed mosaics not far from a stone baptismal font used to baptise his disciples.
As the church is one of the most sacred in North Macedonia, thousands of Macedonian Orthodox Christians gather at Plaošnik during large religious holidays such as Easter and Christmas to celebrate and take part in the liturgies.
References:The Clementinum is a historic complex of buildings in Prague. 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.
