Hesse's Demi Bastion

Hesse's Demi Bastion is a demi-bastion in the British Overseas Territory of Gibraltar. Its full name is the Prince of Hesse's Demi Bastion and was rebuilt in 1730. Behind Hesse's Demi Bastion is the King's Lines Battery and Bombproof Battery is above that. The Moorish Castle's Tower of Homage is at the top of the same incline.

Hesse's Demi Bastion was originally the San Pedro Battery and is situated above Landport Gate. The bastion is located just north of the Moorish Castle's northern front and was part of Gibraltar's important Northern Defences. In 1859 it had six guns.
