The Church of Koimisis tis Theotokou (8, Archimandreiou street), the so-called Archimandreio, of the city of Ioannina, is unknown when it was built. Its existence is certain, however, as early as the 13th century.
It is an old historical Byzantine monastery. The name "Archimandreion" is explained by the fact that this was the seat of Archimandrite, a title then given to abbots of prominent monasteries. The monastery was stavropegial and had developed a rich spiritual life and action as reflected in the very rich collection of manuscripts and printed books as well as in the significant number of sacred icons it posesses.
The current church is a building of the 19th century (approximately 1860).
