Serapeum

500m/550yd north of the tomb of Pergolesi, on the sea, is the so-called Serapeum, an ancient market (macellum), which preserves some columns of its colonnade. Southwest of the Serapeum are baths. In the harbor to the northwest remains of a temple with 14 columns and a sculptor's workshop were discovered on the sea-bed. Above the old town, on the left of the road to Naples, is the Roman Amphitheater (149m/164yd long, 116m/127yd across; seating for 40,000). Particularly impressive are the underground passages which housed the machinery and the wild beasts' dens.
