The church is situated approximately 3,5 km. north of the village Hagios Thomas, on the right river bank of Assopos and close to ancient Tanagra.
It is a simple, two-columned, cross-in-square church with no narthex dated to the middle Byzantine period (probably to the 11th – 12th century, according to Pr. Bouras).
Nowadays, it has suffered many damages.
The interior wall paintings are recent.
