Fuerte de Isla Verde

Fuerte de Isla Verde (English: Green Island Fort) was a military installation formerly located in Algeciras, Spain.

Up to 70 men could be accommodated in the living quarters, located next to the Algeciras Battery, which were divided into separate spaces for the officers and rank-and-file.

In the centre of the island was the main magazine, constructed with thick walls to reduce the risk that a projectile hitting the building would detonate the shells and ammunition stored inside.

A number of firing positions were added to facilitate the use of muskets from the fortress walls and the batteries were paved with flagstones to make it easier to move the gun carriages around.

In 1919 its management passed into the hands of the newly created Board of Harbour Works, which had to bear the cost of relocating the munitions stored there to a new magazine – which it also had to pay for – at Punta de San García.

Military use continued for a while; the fort was reoccupied during the Second World War when two bunkers with machine-gun posts were constructed and manned by a detachment of 40 soldiers, for whom a barracks and kitchen were built.
