History+
The creation of the current square began in 1909 with an urban redevelopment that required the demolition of older buildings. Between 1926 and 1928, systematic excavations commenced, uncovering four temples from the Roman Republic. These temples, the oldest of which dates back to the late 4th or early 3rd century BCE, were surrounded by larger public structures such as Pompey's Theatre. In a curia integrated here, Gaius Julius Caesar was assassinated in 44 BCE. The temples, which cannot be definitively assigned to specific deities, are referred to as Temples A to D.
