In 1618,
Volkert Overlander -
knight,
mayor and advisor of the city of Amsterdam - bought the Lordship from the
Count of Egmond. In 1622 Overlander built the castle of
Ilpenstein. After Overlanders death,
Frans Banning Cocq, who had married his daughter
Maria Overlander van Purmerland, inherited his influence and properties in the north of Amsterdam as well as the title
Free Lord of Purmerland and Ilpendam. After Banning Cocqs death in 1655 the castle belonged to the Amsterdam regent family
De Graeff.
Joost van den Vondel wrote poems about
Pieter de Graeffs and
Jacoba Bickers wedding in 1662 at castle Ilpenstein. Their cousin and brother-in-law
Johan de Witt was also at the wedding. The last residents of the castle were
Christina Elisabeth de Graeff and her husband
Jacob Gerrit van Garderen. In 1872, the castle was sold and demolished and a new building was constructed at the site. Image:Ilpenstein.jpg|Map of Ilpenstein ==See also==
