It was the explosion of being freed from customs that brought this architectural rebirth and was inspired by Greece. One of the architectural techniques that came into use by experimentation was the arch and vault. This renewed architecture art also was the origin of the amphitheater, monumental avenue, and public baths.
Remains of ancient public and private buildings give a very clear picture of Roman architecture. A Roman city's focal point was its forum, usually in the city center at the intersection of the two main streets. An open area bordered by colonnades with shops, it was the city's chief meeting place and the site of the primary religious and civic buildings. One civic building was the basilica, a roofed hall with a wide central area flanked by side aisles and often two or more stories high. The chief temple was at one end of the forum. The standard Roman temple, blending Etruscan and Greek elements, was rectangular with a gabled roof and a deep porch with freestanding columns. .
Roman theaters were semicircular; with a tall stage building joined to a semicircular orchestra and tiered seating area. A framework of piers and vaults supported the theater seats, unlike those of Greek theaters, which depended on natural slopes. The framework enabled Roman theaters to be constructed in the hearts of cities.
Marble gave splendor to buildings, but it was concrete, a Roman invention, that revolutionized architecture and enabled previously impossible construction. Concrete permitted architects to cover vast spaces with great vaults, allowing the construction of great amphitheaters and baths. Romans covered concrete with a variety of face materials, but the most popular was brick. .
The Coliseum.
I chose the Coliseum as an example for Ancient Roman Architecture. It is perhaps the greatest of all amphitheaters. It is a massive Ancient Roman Structure. .

For the time period the Coliseum was constructed in, its dimensions were immense.
