    • bombproof Strong enough to resist the impact and explosive force of bombs or shells striking on the outside.
    • n bombproof In fortification, a structure of such design and strength as to resist the penetration and the shattering force of shells. Such structures are made in a variety of ways, but are usually, at least in part, beneath the level of the ground. They may be entirely of metal, so shaped that shot and shell will glance from the surface without piercing them, or they may be of vaulted masonry, or even of timber covered and faced with massive embankments of earth, the latter forming the most effective shield against modern projectiles. Bomb-proofs are provided in permanent and often in temporary fortifications to place the magazine and stores in safety during a bombardment, and also to afford shelter to the garrison or to non-combatants.
