At the end of the IV century flourished the great
Byzantine culture, including architecture.
The main features of Byzantine architecture:
The use of domes in the Central part of the building. The Byzantines were the first to think up placing domes on «sails», that allowed to have a less cumbersome wall and expand the room.
Inside the temple, under the dome, creates the gallery. From below it was supported by columns.
Minimum of architectural details in the interior and maximum rich design. The walls were clad in marble and covered with gold leaf, mosaics and frescoes.
The windows were usually narrow and with a rounded top.
In the construction of buildings was usually used plinfa, brick and stone.
