Pula

Pottery from the Neolithic period (6000–2000 BC), indicating human settlement, has been found around Pula [1]. The town was elevated to colonial rank between 46 and 45 BC as the tenth region of the late Roman Republic, under Julius Caesar [1]. During that time the town grew and had at its zenith a population of about 30,000 [1]. The city is best known for its many surviving ancient Roman buildings, the most famous of which is its 1st-century amphitheatre, which is among the six largest surviving Roman arenas in the world and locally known as the Arena [1]. The Twin Gates (Porta Gemina) is one of the few remaining gates after the city walls were pulled down at the beginning of the 19th century [1]. It dates from the mid-2nd century, replacing an earlier gate [1].
