This Leitstand was part of the Dirks Admiraal fort and was central to the Flak battery. It was a command post for the air force. All information received about enemy aircraft was processed here and sent on to the artillery operators. The bunker also had 2 open observation posts and a surveillance station. Nowadays, and on Bunkerdag, visitors can clearly see on the inside how this building was constructed. It was based on a combination of two bunker types: the L401 for the base with a FL243 on top for the artillery. There is also an impressive collection of grenades and bombs on display.
