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:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
