The ruins of the Huis ter Kleef castle are located in the city gardens of Haarlem.

The house nearby with a tower called the "Kaatsbaan" was long considered the only building left standing, though recent archeological research suggests that the foundations have older stones than the rest and perhaps it was itself rebuilt after the explosion.

The name "Kaatsbaan" refers to the sport Jeu de paume, an indoor precursor of tennis[2][3] or to "Kaatsen" (Frisian handball), which presumably was once played here, though in the 18th century thiswhat?

In February 2006, the City of Haarlem agreed to a proposal to restore the court at Huis ter Kleef, if the Real Tennis Club Huis ter Kleef could raise the necessary funds (approximately €1,450,000).
