In 1614, the commissioners of Amsterdam began the new fortification of the city with the allocation of plots in the area situated between the Keizersgracht and the Prinsengracht and Reestraat.

The garden houses on the Prinsengracht and empty warehouses were used as storage facilities for the Technical Union.

A modern 176-room hotel was constructed within the buildings, which were joined behind their historic facades.

[4] In 1975, the hotel expanded into two more buildings, adding twenty new rooms and apartments.

The hotel has nine conference rooms, and the salons and reception facilities can accommodate up to 500 people.
