Introduction

BOMBPROOF STORE with GUARDROOM D of a type of bombproof building that is provided with an earth covering as much as possible and that only has the necessary facades on the gorge side. A store is a repository for materiel or artillery etc. and a guardroom is a (reinforced) place of residence for military personnel. With the increase in the range of artillery, the force of projectile impacts and the explosive force of (brisant) shells it became increasingly difficult to withstand attacks. Reinforcement of masonry, application of shock-absorbing masonry systems (among other means by means of arches), shallow slope angles and curved or pointed shapes, use of concrete - and later of reinforced concrete - in increasingly heavy designs, was one of the ways to keep the fortifications resistant to increasing attack force. Moreover, the application of earth coverings proved to be an effective means of absorbing or dampening energy. This is the reason why many masonry or concrete works are provided with an earth layer or a front protection of sand or earth. Depending on the period of construction - and thus the expected impact force of projectiles - these were called 'bombproof buildings' when they were deemed to be able to withstand a predefined number of impacts from heavy calibre.

Description

BOMBPROOF STORE with GUARDROOM D dating from 1878-1880, which are located in the gorge of the round-shaped earthwork on the northeast point. Building D was extended in 1885 on the right side with a volume of rubble or brick concrete. In the facade on the left is a double arched door under a triple relieving arch. In the extension there is an iron door.

Valuation

The BOMBPROOF STORE with GUARDROOM D of the Fort bij 't Hemeltje is of general interest because of:

* Cultural-historical values as part of the Nieuwe Hollandse Waterlinie as designed by C.R.T. Kraijenhoff and initially from 1815 realised by him, Jan Blanken and major-engineer Willem Offerhaus and subsequently by others for approximately 125 years strengthened and improved.

* Military-historical values as part of a continuous military defence line between the former Zuiderzee and the Biesbosch. This consisted mainly of a coherent system of inundation fields and associated inundation means and of firing fields. This system was supplemented with various types of built or constructed (defence) works dating from different periods that served or contributed to the closure of terrain not to be inundated or other accesses.

* Architectural-historical values in particular as an expression of military-strategic building, which is based on: - the system of inundation and access defence (19th century), - the race with increasingly strengthened offensive means (19th century).

This is an example of a bombproof building from the years 1878-1880.

* Ensemble value and situational values as part of the Nieuwe Hollandse Waterlinie. Also because of the functional and physical coherence with the other components of the complex.

* The component is representative (characteristic) because it is a good example of a bombproof building that served as a store with guardroom.

* The component is well preserved because it has retained the characteristics from the building and functional period in architecture and detailing.
