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).
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
