Son Marroig is a country house & museum dedicated to the Archduke Ludwig Salvator of Austria (1847-1915). The Archduke's home at Son Marroig, outside Deia, has been turned into a shrine to his memory, with his photographs, paintings and books and a museum devoted to his life in 1928. In the gardens is a white marble rotunda, made from Carrara marble and imported from Italy, where you can sit and gaze at the Na Foradada ('pierced rock') peninsula, jutting out to sea with a gaping 18-m hole at its centre. Ask at the house for permission to walk onto the peninsula. The house plays host to concerts throughout the year.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
