Roundabout

It is the oldest church in Thessaloniki, and some reports say that it is the oldest Christian church in the entire world. Situated at the intersection of the streets Filippou and Apostolou Pavlou, you enter inside which overwhelm you with the breadth and monumentality. It is similar to the Pantheon in Rome but this building has more interior lighting and the decoration is very spartan.

The altar view of the Rotunda of Galerius, initially a Mausoleum of Roman Emperor Galerius, later a Christian church, and then a mosque. It is now the Church of the Rotunda.
