Amphitheatre

Translated literally from the Greek word, it means "double theatre": amphi – double and theatron – theatre. 

The amphitheatre was an open-air venue with walls on the sides and opened on top, usually with an elliptical shape. The elliptical arena was surrounded by ascending tiered seats for the spectators.

Amphitheatres were designed for spectacular events: gladiatorial combats, fights with animals, games which recreated sea battles, etc.

The best-known facility of this type is the Flavian amphitheatre in Rome, known as the Colloseum. Amphitheatres were found in many cities in Europe and Africa: Verona (Italy), Arles (France), Pula (Croatia).

In 2004 the ruins of the Amphitheatre of Ulpia Serdica were uncovered in Sofia and today can be seen in the basement of the Arena di Serdica hotel. There are ongoing archaeological excavations for the exposure of the amphitheatre. In Bulgaria ruins of amphitheatres were discovered also in Marcianopolis (today Devnya) and in Diocletianopolis (today Hisarya).
