The Monastery of the Dormition of the Most Holy Mother of God or, as it is more commonly called, the Troyan Monastery is the third largest monastery in Bulgaria. It is located in the northern part of the country in the Balkan mountains and was founded no later than the end of the 16th century.
The monastery is situated on the banks of the Cherni Osam near Oreshak, a village 10 km from Troyan in Lovech Province, and is a popular tourist destination.
The main church of the monastery was reconstructed near the end of Ottoman rule during the Bulgarian National Revival period by a master-builder called Konstantin in 1835.
