The Cathedral Church of Saint John stands in the central square of Markopoulo. Following liberation from Ottoman rule, one of the community’s primary concerns was the construction of a monumental church. The first committee for its erection was appointed in 1879. Building works began in 1886 and were completed in 1903.
The original design had been commissioned from the architect Ernst Ziller, but the project was ultimately completed by the architect Aristeidis Razis, who modified Ziller’s initial plan of a domed cross-shaped basilica.
The church’s painted decoration was executed by the renowned iconographer Dimitrios Georgantas, a pupil of the painters Nikephoros Lytras and Nikolaos Gyzis. The official inauguration took place on 21 May 1904, during the tenure of the Archbishop of Athens Theoklitos.
AIGEAS AMKE has supported the church’s operation and the activities of the parish council in various ways, and has contributed to its conservation and protection.
