In the past, the Cromhouthuis garden was a lot longer than it is today. It used to stretch as far as the houses on the Keizersgracht, which were also built by the Cromhout family. 

Like almost all urban gardens in the Golden Age, the design was tightly geometric, dominated by order and symmetry. When the Biblical Museum ‘took up residency’ on the uppermost floors of the Cromhouthuis, references to the Bible were also added to the garden’s design. Landscape architect Jan v.d. Horst incorporated an 18th-century geometric pattern in his design and decorated the garden with plants and trees featured in the Bible. The pools with stepping stones are a reference to the crossing of the Red Sea. The sculpture by Martie v.d. Loo represents the Apocalypse, mentioned in the last book of the Bible.
