Rydboholm Castle (Rydboholms slott) dates back to the Middle Ages. The castle, with the three interconnected wings around an open courtyard, dates from the 16th century. The main building was built in 1548. The castle was reconstructed during the 18th century. Southwest of the castle is a large park in English style from the early 19th century, built by Magnus Fredrik Brahe.
From the 15th century, Rydboholm was the property of members of the Sture family, followed by the Vasa dynasty and later the Brahe family. According to some sources Gustav I of Sweden, who was King of Sweden from 1523 until his death, was born at Rydboholm Castle. From 1520, it belonged to his sister, Margareta Eriksdotter Vasa.References:
The Château des ducs de Bretagne (Castle of the Dukes of Brittany) is a large castle located in Nantes. It served as the centre of the historical province of Brittany until its separation in 1941. It was the residence of the Dukes of Brittany between the 13th and 16th centuries, subsequently becoming the Breton residence of the French Monarchy. Today the castle houses the Nantes History Museum.
The restored edifice now includes the new Nantes History Museum, installed in 32 of the castle rooms. The museum presents more than 850 objects of collection with the aid of multimedia devices. The castle and the museum try to offer a modern vision of the heritage by presenting the past, the present and the future of the city. Night-time illuminations at the castle further reinforce the revival of the site. The 500-metre round walk on the fortified ramparts provides views not just of the castle buildings and courtyards but also of the town.
