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 Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
