Roman Architecture is more or less similar to Greece architecture in the earlier days. After a period of time only the Roman style evolved. They began their architectural style with the internal walls and the domes inside the building. They concentrated much on ornamenting the internal walls of the buildings. They also used the pillar structures for decorations rather than supportive structures. This may be witnessed in many of their temples.They started the domes architecture and the passageway formation. They had much more influence in the field of architecture. Even the Renaissance designs are very much influenced by the Roman Architecture. Lets see some of their structures.
