Roman Architecture: Arches, Columns, Temples, Theaters, Amphitheaters, Baths, Basilicas that the great architects that built them.
As far as Roman Architecture goes, it is difficult to compare it with that of other nations, because the Romans applied architecture to so many and such varied purposes, and so constructed monuments involving both architectural and engineering skill, as to make it doubtful to what class they belonged.
The Romans were the first people to treat architecture as a minister to the numberless needs of a great nation. Before them, except in the Greek theatres, it had served the gods, the royal families, and the dead, alone.
Roman Architecture is our connection with the most advanced civilization of its time. In Rome, ancient history ends and modern history begins; and all her story, both the old and the new, possesses a fascination thus far unequalled in history; and that this fascination should ever be equaled by another nation seems now beyond imagining.
