Scarce antique engraved map of the entrance to Gibraltar from the Spanish mainland, with special focus on the fortifications that defended the British outpost from attack by land.
The map covers the famous Rock (rendered pictorially) and nearby fortifications and town, as well as the no man's land leading up to the area.
The map was published in Paris in 1779, as the French were again fighting the British, this time in the context of the American Revolution. As part of this conflict, Spanish forces besieged Gibraltar in 1779, continuing to do so for 3 years and 7 months, making it one of the longest sieges in recent military history.
The map includes a detailed key labeling items A-Z, &, a, and b.
