The Temple du Change or Loge du Change, formerly used for the stock exchange of Lyon, was originally built after plans by architect Simon Gourdet between 1631 and 1653. It was then rebuilt under the direction of Jacques-Germain Soufflot in 1748-1750. It has been assigned to Protestant worship since 1803, hence its designation Temple.
The first Loge du Change was a small classical building with four arches in front and two on each side. It soon became insufficient for Lyon's money exchange, but was not renovated before 1748.
Soufflot provided plans and elevations for its repair, performed by Jean-Baptiste Roche, an architect he had himself introduced. The flanking terraced houses were torn down, which provided the opportunity to significantly enlarge the building, which has a fifth arch in front, providing, instead of a central pier, a central bay as classical usage demands. Behind the façade rises a large room, as high and wide as the building. It is rectangular with an imperial-styled roof supported on four massive pillars. The first-floor facade was completely rebuilt in Soufflot's uncompromising neoclassical style, unusual for the epoch.
During the French Revolution, the building was abandoned. It became an inn for a moment, before being assigned to the Protestants in 1803. Minor changes were made throughout the nineteenth century, particularly on the interior and the furnishings.
References: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.
