Eastern air raid shelter at Carrow Works

The Eastern air raid shelter at Carrow Works is a purpose-built tunnel constructed in 1939.

The shelter features shuttered concrete entrance portals and is walled in corrugated steel, supported by additional structural steel ribs. It has a horseshoe-shaped plan with entrances and exits at each end.

The exterior includes rounded openings that are filled with later 20th-century wooden doorways, set into shuttered concrete surrounds.

Inside, the north-south tunnels are narrower and formed from ribs with a rectangular section rather than a semi-circular one. This section widens at the south-eastern corner to connect with the east-west tunnel and to accommodate a block of lavatory cubicles. The east-west tunnel is reinforced by timber posts and three brick walls laid in English bond.

There are seven women's lavatories located at the south-eastern corner and eleven men's stalls along the south side of the east-west tunnel, marked by painted signs. The cubicles are made of pine with simple canvas-covered doors and feature hinged wooden benches with holes, under which a bucket could be placed.

The wider south tunnel and the south-eastern corner include concrete bases for perimeter benches, with the wooden seat still remaining at the south-west corner.
