This is a cross form church with cupola, the northern arm of the cross is shorter and ends up in adjacent structure with rib vault. Its frescoes are probably of the late 15th and the early 16th century. It was used as a mosque during the Ottoman occupation. During the Ottoman rule, the church suffered certain modifications, made necessary by its conversion into a functioning mosque, under the name of Dolapli Mescit. Excavations carried out in more recent times unearthed part of road and four tombs, dating from the Hellenistic era. Air raids during World War II waged some serious damages to the church of the Trinity, reinstated with the care of the Greek Archaeological Service after 1980.
