The church of Agios Vlassios
dominates the central square of Xylokastro. It was built on the ruins of an old church with
the same name by late 19th century, following the pattern of the Metropolitan
Church of Athens. It has an eight-sided dome, cylindrical roofs, imposing
columns that support beautiful arches, it is symmetrically proportioned, all of
which gives an impression of magnificence to this temple. The church was
inaugurated in 1908 by the Metropolitan Bishop of Corinth, Vartholomaios
Gheorghiadis. The designs for the floor, the iconostasis and the ambon belong
to archeologists / architects Anastassios Orlandos and Efstathios Stikas. The
icon paintings of the church were
created by Spyros Vassileiou and Aginoras Asteriadis. The town's patron
saint is celebrated on February 11th.
