After the fall of Rome, Christianity flourished along with its architectural forms. The Byzantine architecture consisted much of domed forms and dealt with centers, numerology and light. One of the most magnificent and adventurous buildings of all time is the church of Hagia Sophia (AD 532 - 37) or Divine Wisdom. This was by far the largest of the churches in Constantinople during that era.
The genius part of Hagia Sophia is the fact that the weight of the central dome is dissipated through smaller domes that surround it. The result is a huge central space uncluttered by columns, while the dome itself appears to float in space.
Domed architecture have spread throughout different eras and to different places all over the world, with Hagia Sophia as a big influence.
Hagia Sophia have influenced the design of some of the greatest mosques as well as cathedrals ever constructed.
The Ukrainian St. Michael’s Golden-Domed Monastery, built in 1713, had much more Byzantine-influenced structures before the exterior was rebuilt in the Ukrainian Baroque style in the 18th century, though the interior remained in its original Byzantine style. The original cathedral was demolished by the Soviets in the 1930s, but was reconstructed and opened in 1999. The overall structure is still very much consisting of a hill of domes, like Hagia Sophia.
