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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
