One of the farms of the medieval village was given as a gift to Johan Skytte by Prince (later King) Gustavus Adolphus.

Skytte was the tutor of the future king and would later become, among other things, chancellor of Uppsala University and member of the Privy Council of Sweden.

During the second half of the same century Grönsö was owned by the medical doctor David von Schultzenheim, under whose ownership several of the interiors were remade in a simple form of Neoclassical style, sometimes referred to as "Gustavian" after Gustav III of Sweden.

Its style is reminiscent of that of William Chambers and it is decorated inside with shells and rocks from East Asia.

[2] An apple orchard was established at the estate in 1623 by Johan Ludvigsson, former royal gardener to King Charles IX of Sweden.
