Pelișor Palace was built in 1899–1902 by order of King Carol I, as the residence for his nephew and heir, the future King Ferdinand (son of Carol's brother Leopold von Hohenzollern) and Ferdinand's consort Queen Marie.
In 2006, it was decided that the entire complex, including Pelișor, long a museum and tourist site, is the legal property of the King Michael I of Romania. The royal family was to assume legal possession of it and lease it to the Romanian state, so that it will remain in its current status. The main castle of Peleș is already under lease, but negotiations for other villas and chateaus are ongoing. King Michael I of Romania maintained that Pelișor would remain a private residence for the royal family.
Pelișor was designed by the Czech architect Karel Liman in the Art Nouveau style; the furniture and the interior decorations were designed mostly by the Viennese Bernhard Ludwig. There are several chambers, working cabinets, a chapel, and 'the golden room'. Queen Marie herself, an accomplished artist, made many of the artistic decisions about the design of the palace, and participated in its decoration, including as a painter. Queen Marie considered Art Nouveau a weapon against sterile historicism, creating a personal style combining Art-Nouveau elements with Byzantine and Celtic elements.
Pelișor Castle hosts today a museum.
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.
