In the 17th century, Copenhagen had become home to a sizeable garrison. A military church was built at Kastellet in 1670 but its modest size only allowed it to serve the personnel at the fortress. The rest of the troops in the city had to use Church of Holmen, a former anchor forge which had been converted into a naval church in 1619.
When Sophie Amalienborg burned down in 1689, its chapel survived the flames and was subsequently put at the disposal of the Army. However, the small building which had been built for members of the royal court only served as a temporary solution. Christian V therefore provided a tract of land at Dronningens Tværgade for the construction of a new church for the Army and military engineer Georg Philip Müller completed a set of renderings in 1697. When Frederick IV ascended the throne in 1699, he moved the project to a site in the southernmost section of Sophie Amalienborg's former gardens. Construction began in 1703, still to Müller's design but under the supervision of Domenico Pelli. The following year it was decided to built the church to a larger and somewhat modified design and the project was taken over by General Master Builder Wilhelm Friedrich von Platen. The church was inaugurated on 24 March 1706.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
