Bayonne has been inhabited since roman times, when it was known as Lapurdum. Its medieval fortifications were improved by Louis XII, and Francois I, enabling the town to defend itself against a Spanish army in 1523.
Vauban visited Bayonne sometime in the 1670's, and planned more improvements to the fortifications, including the construction of additional demi-lunes and a large, quadrangular citadel to the north of the river Adour. The city itself, which lies to the south of the Adour and is bisected by the river Nive, was surrounded by a wall of 9 rather eccentric bastions.
The citadel was designed from scratch by Vauban, and is a large square work with four bastions. It saw action against the invading British forces at the end of the Peninsular War, when it was taken by General Hill after a determined defence by the French.
The fortifications of Petit Bayonne, the eastern half of the town, had four bastions and one gate, the Porte de Notre Dame. To the west, Grand Bayonne had five bastions and two gates, the Porte d'Espagne and the Porte de la Poterne. The first gate is unusual in that it enters the walls through a bastion, not through the courtine as is normally the case.
The size and shape of each bastion is very different, and there are varying lengths between them, which makes the fortifications seem less regular than some. This is probably due to the way Bayonne was fortified in several stages, with improvements added gradually.References:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
