View of the two Blokhuizen in the Amstel, 1651-1654

View of the two Blokhuizen in the Amstel outside Amsterdam, built to defend the city after the failed attack by Willem II on Amsterdam on 30 July 1650. After they were completed in 1651, they were demolished again in July 1654. On the left and right of the Blokhuizen, two hamei. On the water, various boats sail. In one boat stands a small tree, and on another, the mast is struck. From a raft or jetty, children swim and a figure relieves himself in the front right. Between the two Blokhuizen in the background, the contours of the city with the mill De Joffer and the Zuiderkerk.
