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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
