Tarragona's Roman Circus can be reached via a tunnel from the Praetorium (buy a joint ticket). Excavation work here is on-going - and fascinating as its beginning to reveal the Circus terraces where crowds would sit. Here Roman chariot racing and other big crowd events would have been held. Tarragona's Roman circus dates from Domitian's reigh in the 1st century AD. Superbly preserved, Tarraco's Roman circus stretches 324 metres in length and almost 115 metres in width.
Moving down towards the sea (although best viewed from the top of the Praetorium) is Tarragona's Roman Amphitheatre. Again its wonderfully intact and would have been a centre for Roman theatre and circus. Its location on the seashore is deliberate - outside the city walls for ease of access, plus unloading of animals from the water.
