The Widerstandsnest 53 complex, to which these three bunkers belong, formed the northwestern Sperre access point to the Festung Hoek van Holland. Various types of bunkers can be found in the immediate vicinity. For example, to the east of the N211 is a residential area built on several small mounds that hide 3 barracks bunkers, 2 munitions bunkers and a kitchen/mess hall combination.
A type 501 barracks bunker can be found in the tea garden at the Intratuin garden centre. This was a simple type of bunker that provided shelter for 9 soldiers and 1 officer, the smallest unit in the German army, called a ‘Gruppe’. Each soldier had a space of 2m2, which had to include furniture. They slept in 3-high bunk beds, had cupboards for their personal effects and used tables and stools to sit at. A stove was also installed for heating and cooking.
