The Holy Trinity Church (also known as Church of Agia Triada) is one of the most impressive ecclesiastical monuments in Rhodes. It is located on Knights Street in Rhodes Town.
The stone-built church was originally built possibly sometime during the 15th century. It has a cruciform architecture and a tiled dome. Findings suggest that it was initially dedicated to Saint Michael and it was later converted to a mosque during the Ottoman occupation years. Lots of the church's ruined indoor murals and frescoes that dated to the early 16th century were restored during the Venetian occupation period. The church was also partly destroyed during the Second World War and restoration works took place after the 1980's.
Ruines that date to the Hellenistic period have been found at the location of the church.
