Dating from the mid 18th century, it is now a museum housing the Kastrupgård Collection (Kastrupgårdsamlingen) of modern art, which is owned and operated by Tårnby Municipality.
[1] Kastrupgård was designed in rococo style by sculptor and architect Jacob Fortling (1711–1761) for his own use.
[2][3] Tårnby municipality decided in 1968 to convert Kastrupgård into a museum and establish an art collection.
In 2013, the municipality of Tårnby was in charge of extensive refurbishment and redevelopment, so that there is now a museum in all the four wings of the site.
It is also home to a collection of works by painter Theodor Philipsen (1840–1920) and of faiences from Kastrup Værk.
