The Caixa de Rotllan (meaning 'Roland's Tomb' in Catalan language) is a dolmen dating back to the Neolithic period, during the second half of 3rd millennium BC.
A legend holds that Roland lived in Vallespir and that, after his death at the Battle of Roncevaux Pass, his horse Veillantif carried Roland's corpse back to Vallespir and buried him under this dolmen. Dolmens are actually tombs, but they were erected many centuries before the legendary knight's adventures.
The Caixa de Rotllan is made of three upright stones making a H-shape, supporting a thick roofing stone and delimiting a rectangular, medium-sized chamber.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.
