Tejisi village, in Tsalka municipality, at "Aya Konstantin" or the St. Constantine's Church, is surrounded by a pile of megalithic walls, made of boulders. A boulder weighing up to 7 tons is on the western wall of the fence.
The one-nave church must once have been a two-room building with a single roof. Now only one roof room remains. The entrance is quite low, low enough you have to bow to enter with a sense of deference.
Inside the church, a 4-meter-high stone menhir and a cross is carved on the facade. The peculiar stone is magnetic on one side which is strange since the stone is mostly basalt, which is not magnetic.
The second church is in the center of Tejisi. The church had a megalithic wall, but it has since been demolished. The lower blocks are aligned in a polygonal arrangement, a similar characteristic of the oldest buildings found in South America.
