The Pula Arena is a Roman amphitheatre located in Pula, Croatia. It is the only remaining Roman amphitheatre to have four side towers entirely preserved. It was constructed between 27 BC and AD 68, and is among the world's six largest surviving Roman arenas. The arena is also the country's best-preserved ancient monument.
The amphitheatre is depicted on the reverse of the Croatian 10 kuna banknote, issued in 1993, 1995, 2001 and 2004.
