For over 300 years, until 404 A.D., the citizens of Rome were able to visit the 50,000-seat Colosseum daily and view a wide variety of deadly gladiatorial combats and sporting events. Most modern stadiums draw their inspiration from this true Wonder of the ancient world.

The Colosseum is of great defensive value. It increases your national borders, and also increases attrition among enemy invaders. You can also build Forts and Towers more cheaply.
