Nowadays the Hofvijver is adjoined in the west by the Buitenhof, but until the 19th century that side was adjoined by houses. The pond is encircled by fairly high quays, but is very shallow on some points. In 2004 an underwater gate was built to make sure that nobody could swim to the prime minister's office without being detected. His office, the Torentje ("Little Tower"), adjoins the Hofvijver as it is located on the Binnenhof.
