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:
Château de Falaise is best known as a castle, where William the Conqueror, the son of Duke Robert of Normandy, was born in about 1028. William went on to conquer England and become king and possession of the castle descended through his heirs until the 13th century when it was captured by King Philip II of France. Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840 it has been protected as a monument historique.
The castle (12th–13th century), which overlooks the town from a high crag, was formerly the seat of the Dukes of Normandy. The construction was started on the site of an earlier castle in 1123 by Henry I of England, with the 'large keep' (grand donjon). Later was added the 'small keep' (petit donjon). The tower built in the first quarter of the 12th century contained a hall, chapel, and a room for the lord, but no small rooms for a complicated household arrangement; in this way, it was similar to towers at Corfe, Norwich, and Portchester, all in England. In 1202 Arthur I, Duke of Brittany was King John of England's nephew, was imprisoned in Falaise castle's keep. According to contemporaneous chronicler Ralph of Coggeshall, John ordered two of his servants to mutilate the duke. Hugh de Burgh was in charge of guarding Arthur and refused to let him be mutilated, but to demoralise Arthur's supporters was to announce his death. The circumstances of Arthur's death are unclear, though he probably died in 1203.
In about 1207, after having conquered Normandy, Philip II Augustus ordered the building of a new cylindrical keep. It was later named the Talbot Tower (Tour Talbot) after the English commander responsible for its repair during the Hundred Years' War. It is a tall round tower, similar design to the towers built at Gisors and the medieval Louvre.Possession of the castle changed hands several times during the Hundred Years' War. The castle was deserted during the 17th century. Since 1840, Château de Falaise has been recognised as a monument historique by the French Ministry of Culture.
A programme of restoration was carried out between 1870 and 1874. The castle suffered due to bombardment during the Second World War in the battle for the Falaise pocket in 1944, but the three keeps were unscathed.
