The Lonja de la Seda or Llotja de la Seda (Silk Exchange) is a late Valencian Gothic-style civil building in Valencia. It is a principal tourist attraction in the city and UNESCO World Heritage Site.
Built between 1482 and 1533, it is an exceptionally well-preserved example of a secular building in late Gothic style of outstanding artistic value. It bears eloquent witness to the role played in the Mediterranean and far beyond by the merchants of the Iberian Peninsula in the 15th and 16th centuries.
la Lonja is composed of three parts. The main hall, Sala de Contratación (The Trading Hall), is a large lavishly decorated space supported by gorgeous twisted columns. This was the financial centre of La Lonja, where the merchants work out contracts. The side-wing is named the Pavilion of the Consulate, and this was the seat of the Tribunal del Mar - the first marine merchant tribunal to ever be formed in Spain. The first two floors were the main function rooms, with the upper one hosting a richly decorated ceiling. These rooms are still maintained original furnishings. On occasion, the Tribunal would imprison merchants for debts in the central tower of La Lonja - the third part of the structure.
In addition to being a very representative example of medieval places of commerce, the building incorporates elements of the new architectonic language that developed in Europe at the end of the 15th century incorporating the most daring progress in the field of construction techniques (admirable twisted columns and vaults of remarkable complexity, all in freestone of the highest quality).
The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
