Founded together with the city Korçë itself, the mosque was built in the 15th century on the foundation of a former church during the Istanbul Conquest. The minaret was torn down during the communist period and rebuilt in 2014.
The connected island of Agios Ahillios is a site steeped in history. Indeed, in the 10th century, this islet was one of the centres of Bulgarian imperial power, at which time it preserves the massive ruins of the Basilica of St. Achilles. South of the site are still several other churches and monasteries.
On this relatively small island of Lake Megali Prespa stretching into northern Macedonia, Albania and Greece, a large number of historical and cultural monuments are concentrated. The Golem Grad island has been inhabited continuously for 2000 years and the monastic life was thriving there from the 10th century until the 14th century. Thus, there are no less than seven remains of churches. Among them, the Church of St Peter of Golem Grad, the only fully preserved church. Built around 1360, its reconstruction was last carried out in 1934. The church has many frescoes to admire inside.
