The main building, with its 50 rooms, was designed by the Westenholz' brother-in-law, the architect Torben Grut, in a neo-baroque style.

In 1942, Magleås was bought by papal chamberlain and count Christopher de Paus, who had sold his estate Herresta in Sweden in 1938 to a relative and who died in 1943.

Magleås was inherited by Thorleif Paus, who sold the property in 1945 to the Catholic Church in Denmark.

For some years, it was used as a college, but today it serves as a conference hotel as well as representative purposes for the Catholic Church in Denmark.
