The position of Surrentum was very secure, protected by deep gorges. The only exception to its natural protection was on the south-west where it was defended by walls, the line of which is necessarily followed by those of the modern town. The arrangement of the modern streets preserves that of the ancient town, and the disposition of the walled paths which divide the plain to the east seems to date in like manner from Roman times. No ruins are now preserved in the town itself, but there are many remains in the villa quarter to the east of the town on the road to Stabiae, of which traces still exist, running much higher than the modern road, across the mountain; the site of one of the largest (possibly belonging to the Imperial house) is now occupied by the Hotel Vittoria, under the terrace of which a small theatre was found in 1855; an ancient rock-cut tunnel descends hence to the shore. Remains of other villas may be seen, but the most important ruin is the reservoir of the (subterranean) aqueducts just outside the town on the east, which had no less than twenty-seven chambers each about . Greek and Oscan tombs have also been found.
