AROW Street is a tunnel within the Rock of Gibraltar, excavated in 1942 during the Second World War. Planned in January 1942, it was specifically designed large enough to accept Army trucks carrying ammunition, similar in scale to Gibraltar’s Great North Road. Along its length, the tunnel incorporates chambers that were intended to contain stores of ammunition and other supplies, forming part of the territory’s internal wartime logistics network. The tunnel runs entirely inside the Rock behind the east side, which overlooks the Mediterranean. One wartime entrance was via Monkey’s Cave. Soldiers from the Royal Electrical & Mechanical Engineers would enter AROW Street through Monkey’s Cave and follow this internal road to reach their instrument workshop located further inside the Rock. Their cave workshop had windows, allowing work by natural light and providing views of the Straits of Gibraltar. The name “AROW” comes from the initials of Lieutenant Colonel Arthur Robert Owen Williams of 178 Tunnelling Company, Royal Engineers, who was in charge of tunnelling operations in Gibraltar during the war. AROW Street is recorded as a tunnel in Gibraltar, constructed in limestone, with its owner listed as the Government of Gibraltar.
