The Château de Rosanbo, overlooks the Bô river valley. The origin of its name stems from this fact, as in Breton it means 'rock on the Bô'. The château, which was in the past the stronghold of the Coskaër de Rosanbo family, then later of the Le Peletier de Rosanbo family, is square in shape and has been developed and re-fashioned throughout its history. In the 14th century, a fortified castle was built on a strategic headland, located 4 miles from the bay of Saint-Michel-en-Grève in order to prevent the ascent of the Bô by invaders. In the 16th century, it was extended with a Gothic manor.
The buildings were further extended in the 18th Century by Louis Le Peletier de Keranroux, first president of the Paris parliament and husband of Geneviève de Coskaër (the last inheritor of that name). At the time of this redevelopment, the architect Joubert added a gallery to the château and a corner room overlooking the valley. The old kitchen was transformed into a wood pannelled dining room and, on the floor above, additional new space allowed small rooms such as private bathrooms and boudoirs to be created. At the end of the 19th Century, new suites were designed by the architect Lafargue, who was also responsible for the restoration of the châteaux of Josselin and Chenonceaux.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.
