Sitting on Plaošnik next to St Pantaleon is a church in ruins, built in the 5th century. It is important as an architectural solution since it has a four-leaf shape. Central solutions like this were built in Syria and Mesopotamia and they became customary much later in Europe, in the 10th century. It shows that Ohrid had great ties with the early Christian centers and that there was an exchange of artists and minds. It has a three-leaf shape on the outside and four-leafs on the inside and it had a big dome in the center (notice the 4 huge basis of columns). There is also a small baptistry to the right with a four leafed shape with some excellent mosaics.
