Mesen Castle was an important noble residence in Lede, Belgium, today partly ruined and completely abandoned.

The 18th-century facade was designed by the Italian architect Giovanni Niccolò Servandoni for the 4th Marquess, Emmanuel de Bette.

[1] The main facade has a dorian colonnade with balustrade and large pediment, with heraldic crest of the house of Bette, holding lions.

The girls and ladies lived together in a very close community, leaving only for Christmas, Easter and summer vacations, and having visitors once a month.

[3] By 2015 the town council of Lede, Belgium, decided to demolish the remaining buildings after prior partial demolition to make place for a new sanatorium in 2010.
