St Aubin's Fort was developed on a rocky islet off the coast at the western end of St Aubin's Bay. It was finished in the 1540s. At that time St Aubin was the primary port on Jersey and the fort controlled the entrance. In the 17th century the Civil War the Parliamentarians turned it into a stronger fortress, by building a bulwark on it, and when the Royalists regained possession they replaced this with granite ramparts and added a storey to the tower. In the 18th century, and again in the 19th, the fort was rebuilt twice, but in peaceful Victorian times it was let as a summer residence. In the Second World War the Germans strengthened the fort with turret guns and concrete casemates.
A causeway extends from the road in front of the Royal Channel Islands Yacht Club to the fort, and one can walk out at low tide. However, the fort itself is closed to the public. Jersey's Sea Scouts use the fort as a headquarters, storing their sails and other equipment in a German bunker built into the fort. They have also converted a room in the tower into a classroom.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
