The church of Agia Thekla in Kallirachi was built in 1898 and opened in 1953. It is one-room timber-framed church with a later addition of a narthex. It is the cemetery church of the community. A special feature is the built-in altar in the niche of the sanctuary due to lack of space.

The memory of Agia Thekla is celebrated on 24 September.
