In OLYMPIA's Dynamo Room, the underside of
the protective deck can be plainly seen. The space apparently also
served as an ammunition handling room, since the ammunition hoist for
the forward turret ends at this space, as do hoists for other guns. The
ammunition was apparently raised vertically to this level, and the
moved horizontally to the appropriate hoist. The reason for this space
with its required horizontal movement of ammunition was to prevent an
enemy projectile or an accidentally dropped shell from falling
directly into the vicinity of the magazines themselves, In other words,
the hoists did not connect the magazines to the topside level of the
ship directly.
Entering the space via ladder, the visitor will find themselves in a
fairly open space, with space for the various pieces of electrical
apparatus. Ventilation ducts run along the underside of the protective
deck, which angles down forming the exterior bulkhead of the space.
directly aft of the ladder by which the visitor enters is the ammunition
hoist for the forward turret. Aft of that is the hoist leading down to
the handling room and magazines below.
