What is the height of the Colosseum?

The height of the Colosseum is 48 meters.

This is the approximate height of the surviving outer wall at its tallest point, equivalent to about 157 modern feet. The building’s height made it an imposing landmark in ancient Rome, even though much of the upper structure has disappeared.

The amphitheatre had multiple architectural levels framed by arcades and columns. Its exterior used travertine limestone, tuff, and brick-faced Roman concrete, combining heavy materials with a carefully engineered system of arches and vaults.

The 48-meter figure is often confused with estimates for other monumental structures or with the Colosseum’s dimensions along the ground. Its length was about 189 meters and its width about 156 meters. Damage from earthquakes, stone removal, and weathering means the surviving height is an architectural measurement, not necessarily the exact maximum height of every original feature.
