'''Mumbles Lighthouse''', completed in 1794, is a [[lighthouse]] located in [[Mumbles]], near [[Swansea]].<ref name="Trinity">{{cite web |url=http://www.trinityhouse.co.uk/lighthouses/mumbles.html |title=Mumbles |publisher=[[Trinity House]] |access-date=12 April 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110414061333/http://www.trinityhouse.co.uk/lighthouses/mumbles.html |archive-date=14 April 2011 }}</ref> The structure, which sits on the outer of two islands off Mumbles Head, is clearly visible from any point along the five mile sweep of [[Swansea Bay]]. Along with the nearby lifeboat station, it is the most photographed landmark in the village.

The tower has two tiers and initially two open coal fire lights were displayed.<ref name="Trinity"/> These open coal fire lights were difficult to maintain and were soon replaced by a single [[Kerosene lamp|oil-powered light]] within a cast-iron [[lantern]].<ref name="Trinity"/>

In 1860, the oil-powered light was upgraded to a [[dioptrics|dioptric]] light and the [[Mumbles Battery]], a  [[fortification|fort]] that surrounds the tower, was built by the War Department.<ref name="Jenkins">{{cite web |url=http://www.cblights.com/lights/themumbleslighthouse.html|title=The Mumbles Lighthouse |work=Chesapeake Bay Lighthouse Project |author=Matthew Jenkins |access-date=12 April 2011}}</ref>

In 1905, an [[characteristic light|occulting]] mechanism, where the light was made to flash, was fitted. This was partially automated in 1934.<ref name="Jenkins"/>

By 1977, the cast-iron lantern had deteriorated beyond repair and was removed. A different lantern was added in 1987.<ref name="Jenkins"/>

In 1995, the main light was replaced and an array of [[Photovoltaic module|solar panel]]s and emergency monitoring equipment were added.<ref name="Trinity"/>
