Roman Theatre, Mérida

Commissioned by consul Marcus Vipsanius Agrippa in 16-15 BC in Emerita Augusta, capital of Roman Lusitania (modern Merida, Spain). The semicircular cavea (86.63 m diameter) seated approximately 6,000 spectators across three social tiers. The scaenae frons was rebuilt under Trajan in the early 2nd century and renovated again under Constantine (330-340 AD). Part of Merida's UNESCO World Heritage Site (1993), it hosts the International Festival of Classical Theatre since 1933 and is considered one of the 12 Treasures of Spain.
