The castle is the headquarters of SES, the world's largest satellite operator in terms of revenue and the largest component of Luxembourg Stock Exchange's main LuxX Index.

Since its acquisition by SES, the company has built a large commercial and industrial centre on the castle estate.

It should not be confused with Berg Castle, located in nearby Colmar-Berg, which serves as the communal headquarters for Betzdorf.

In July of that year, the castle served as a base camp for 3,000 Scouts celebrating the 75th anniversary of the movement's foundation.
