Sailboats glide past one of the ancient world's most remarkably preserved Roman amphitheaters in this evocative 1910 view of Pola (today's Pula, Croatia) seen from the harbor — the elliptical stone colosseum rising dramatically behind a busy quay of steamships and traditional Adriatic lateen-rigged craft, fishermen and strollers dotting the waterfront promenade in the afternoon light. Built in the 1st century AD under Emperor Augustus and Vespasian, the Pula Arena is one of only six Roman amphitheaters in the world with all four side towers intact; at the time of this photograph Pola was a major Austro-Hungarian naval base and the arena stood just meters from the water's edge, making it one of the most photographed subjects in the entire Adriatic. Publisher F. W. Schrinner of Pola issued the card using a photograph by Prof. A. Beer of Klagenfurt, the copyright line reading Gesetzlich geschützt. 1910 — legally protected 1910 — placing this firmly in the golden age of Central European postcard production.
