The Porta San Paolo is one of the southern gates in the 3rd-century Aurelian Walls of Rome. The Via Ostiense Museum is housed within the gatehouse.
The original name of the gate was Porta Ostiensis, because it was located of the beginning of via Ostiense, the road that connected Rome and Ostia where functioned as its main gate. Via Ostiense was an important arterial road, as evidenced by the fact that upon entering the gate of the same name, the road split, with one direction leading to the famous Emporium, the great market of Rome.
The gatehouse is flanked by two cylindrical towers, and has two entrances, which had been covered by a second, single-opening gate, built in front of the first by the Byzantine general Belisarius (530s–540s).
The structure is due to Maxentius, in the 4th century, but the two towers were heightened by Honorius. Its original — Latin — name was Porta Ostiensis, since it opened on the way to Ostia. Later, it was renamed to the Italian Porta San Paolo, because it was the exit of Rome that led to the Basilica of St. Paul Outside the Walls.
In 549, Rome was under siege; the Ostrogoths of Totila entered through this gate, because of the treason of the Isaurian garrison. On 10 September 1943, two days after the armistice between the Allies and Italy had been agreed, Italian military and civil forces tried to block German seizure of the city, with 570 casualties.References:
Trullhalsar is a very well-preserved and restored burial field dating back to the Roman Iron Ages (0-400 AD) and Vendel period (550-800 AD). There are over 340 different kind of graves like round stones (called judgement rings), ship settings, tumuli and a viking-age picture stone (700 AD).
There are 291 graves of this type within the Trullhalsar burial ground, which occurs there in different sizes from two to eight metres in diameter and heights between 20 and 40 centimetres. Some of them still have a rounded stone in the centre as a so-called grave ball, a special feature of Scandinavian graves from the late Iron and Viking Age.
In addition, there is a ship setting, 26 stone circles and 31 menhirs within the burial ground, which measures about 200 x 150 metres. The stone circles, also called judge's rings, have diameters between four and 15 metres. They consist partly of lying boulders and partly of vertically placed stones. About half of them have a central stone in the centre of the circle.
From 1915 to 1916, many of the graves were archaeologically examined and both graves of men and women were found. The women's graves in particular suggest that the deceased were very wealthy during their lifetime. Jewellery and weapons or food were found, and in some graves even bones of lynxes and bears. Since these animals have never been found in the wild on Gotland, it is assumed that the deceased were given the skins of these animals in their graves.
