The cemeterial temple of St Nikolaos and St Charalambos at MIliarisi is very special because it is dikonchos (double-niche), a type that is rare. The type of dikonchos church differs from the two-aisled as there is a common roof for both aisles, without interference of wall between the aisles. The dikonchos temple has its roots from the twin pagan sanctuaris of the Ancient Times and especially the worship of Dioscuri. It is also connected to funerary purpose.
The temples of the dikonchos type were usually built on the banks of rivers and streams with water, or cemeteries, like here. It is believed that this had to do with the belief that water is the barrier that prevents the dead pass into the world of the life people. The temple bears frescoes that have a funerary character (14th century).
