Sigri, the westernmost fishing village of the island, was a settlement with a predominantly Turkish population during the centuries-long Turkish rule. The village church, dedicated to the Holy Trinity, was built in 1870 by the Turks and was used as a mosque until the exchange of populations in 1923, when it was converted into a Christian church. Its architect was Ioannis Demiris from Eres, who from the beginning had not given it an orientation towards Mecca, but towards the east, hoping that one day the temple would be converted into a Christian one.
The building is tall, imposing and beautiful, built with stones from the sharmosak quarry. The temple is housed on the second floor, as the ground floor has been used as a warehouse since it functioned as a mosque. Thus, in order to enter it, one climbs a tripartite staircase. The rhythm given internally did not allow the universal arrangement of the space with the construction of columns, but wooden pews were placed which shaped the space into a three-aisled basilica. The roof of the temple remained as it had a four-sided wooden tile roof.
Particular glamor is given to the building by the numerous large windows in the Arabic and Byzantine style per row, made of sarmosacopetres. The two tall columns that adorn the western face of the building, on which the three large Arabic-style arches rest, give the building grandeur and imposingness.
The temple has a matroneum, supported by four columns. The wooden iconostasis of the church has no special decorations and is the work of 1923 by the craftsman Dimitrios Kalchas or Kalfamitros from Tenedos, while the pulpit is the work of the craftsman Eleftherios Havaranis from Eresos. The temple also keeps valuable icons from Asia Minor during the exchange of populations.
