The Huis ter Kleef castle was probably built in the late 13th century. In 1403 it was given to Margaret of Cleves (c.1375-1411), and has since retained that name. During the Siege of Haarlem in 1572 it was the headquarters of the Spanish army, under the leadership of the duke of Alva. It was blown up in 1573 and badly damaged, the rubble was used for city expansion. 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 property changed hands several times until it was purchased by the city of Haarlem in 1713. Stones from the central castle ruin can still be seen in surrounding buildings. The Kaatsbaan was used as a residence for former owners and is now also in use by the city gardens.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
