Nun's Well

Nun's Well is an underground water reservoir at the southern tip of Gibraltar featuring two vaulted chambers supported by pillars. Access is gained through steps on the eastern side, with a fortress-like building constructed above to provide modern entry to the historical chambers.

The underground reservoir dates from the Moorish period and served as a water source for military forces in Gibraltar over several centuries. Later modifications included the addition of a fortress-style building to ensure permanent access and protection of the historical structure.

The name comes from its proximity to the Shrine of Our Lady of Europe, though there is no actual link to nuns. Visitors can sense the spiritual importance of this location near this religious site.

The site is straightforward to navigate and the stairs provide safe access to the underground chambers. Visitors should expect older stone steps and limited space in the chambers, so comfortable shoes and a flashlight are helpful.

Water in the reservoir comes from multiple sources including rainfall, street drainage, and sea spray, creating a complex water system. This combination of different water sources made the structure particularly valuable in this arid climate.
