Prem Castle was built before 1213. After the Udo Knights there were many owners, among them the Walseeis, Hallers, Habsburgs, and Porcia Dukes. This compact two-storey building with a ground plan in the shape of the letter L has a Romanesque nucleus with an extension and a smaller yard protected with a wall. The inner yard was decorated with Renaissance arcades. In the middle of the yard stands a small well. The entire structure is additionally protected with exterior Renaissance walls and cylindrical towers. A large cistern stands in the larger courtyard, between the castle and the exterior walls.
The area on the ground floor of the castle is cross rib-vaulted. Above it is the castle chapel, which was set up at the end of the 14th century. Modest console masques in it are reminiscent of Parler workshops. A large hall on the upper floor decorated with a wooden promenade gallery was rearranged before the last war by its owners, the Zuccolini family from Trieste. It was painted with unusual decorative frescoes on a dark background.
The castle houses local museum collections. The cylindrical towers of the outer walls have been arranged.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.
