Plaošnik is an archaeological site and holy place in Ohrid. The church was built by St. Clement in the year 893 on the foundation of an early Christian basilica, and dedicated to St. Panteleimon. It was here that the Ohrid Literary School, a center of Slavonic literary and cultural activity where more than 3,500 disciples were educated. St. Clement was buried in this church, in the tomb which was built by his own hands.
After the advent of the Ottoman Empire, St. Clement's church was converted into a mosque, known as the Imaret Mosque, of which only a small enclosure remains. The mosque was built as an endowment and a memorial by Sinan Chelebi, member of the distinguished Turkish family of the Ohrizade. 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.
Apart from the church's many reconstructions during the time of the Ottoman Empire, it has undergone extensive reconstruction and excavation in the contemporary period.
On Plaošnik has been discovered the baptistery of the five aisle basilica with hooked crosses (swastikas) on the mosaic floors which date from the period between 4th and 6th century. It is assumed that this early Christian basilica at Plaoshnik upon which the Kliment's monastery was built in the 9th century, was dedicated to St. Paul the Apostle who preached Christianity in Lychnidos (present-day Ohrid) in the 1st century A.D.
On 10 October 2007, a deposit of approximately 2,383 Venetian coins was discovered by archaeologists while excavating the monastery.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
