Mechelen town hall on the Grote Markt consists of two parts: the cloth hall with unfinished belfry and the Palace of the Great Council. The cloth trade went into decline in the 14th century and there wasn't the money to complete the building. For two hundred years the belfry was no more than a shell, until it was eventually provided with a temporary roof in the 16th century. The belfry is now a UNESCO world heritage site. On the right of the belfry you can see the oldest part of the town hall, the remains of the earlier cloth hall. On the left is the Palace of the Great Council. The Great Council never actually met here, because this wing was only completed in the twentieth century in accordance with the original sixteenth-century plans of the then leading architect Rombout Keldermans. The interior of the Town Hall is well worth seeing.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.
