The C6th Church in Ruweiha is known by the name of its patron Bizzos. It is an exceptionally large building that has a wide arch span facilitated by the use of piers springing from cross-shaped bases, rather than the more usual arrangement of columns and capitals. In the 1990s it was well preserved, but several families lived in houses in the ruins of the structure. The mausoleum of the patron lies on the edge of the church compound.
Ruweiha is unusual for being the only village that had two churches with a bema, however in this case the nave-platform seems to have been dismantled when the church was superseded by a new, larger church in the village. Only the south and east sides of the building are still extant, but these survive in good condition and show that this was a substantial church, even if the later building in the village was even more impressive.
