Located at Whiteford Point on the north west of the Gower Peninsula, a 61 foot tall, cast-iron lighthouse tower stands promptly in the middle of the sea.
The historic Whiteford Lighthouse, stands just above low-water level as is the only one of its kind left in Britain.
The lighthouse was last in use in 1933, but now can be found as a strong Welsh landmark.

This piece of history was constructed by the Llanelli Harbour and Burry Navigation Commissioners in 1865 to mark the south side of the channel to the port of Llanelli, replacing an earlier wooden structure built in 1854.
The first known cast-iron British lighthouse was at Swansea Harbour and was built in 1803, the architect was William Jernegan, and the plates were cast at the Neath Abbey Ironworks.
The cast iron lighthouse is believed to be the last remaining cast iron lighthouse found in Britain.
Other cast iron lighthouses in the world are located in Vermont, Netherlands and Jamaica.
The lighthouse remained in use until 1933 but now is out of use and owned by Carmarthenshire County Council.
It stands proudly on a vast two mile expanse of beach leading out along the edge of the Loughor Estuary and over looks Llanelli, Burry Port and the Gower.
The name Whiteford is considered to derive from the Danish words Hvit-Fford. The northern boundary runs along the limit of the sand and shingle bank upon which a lighthouse stands on.
Across the estuary are Burry Port and Llanelli beaches and you are able to access the lighthouse by foot and many locals do.
If you are interested there are safety measures that you must take, here is advice from Oh What A Night, they say: "Because the base of the lighthouse is situated half a mile into the Loughor estuary off the tip of the peninsula, it is only accessible 90 minutes either side of low tide.
"Check the tide times available here and aim to get down there before low tide. The walk to the lighthouse will take at least an hour so factor this into your hike before your start.
"Please don’t risk getting caught by the incoming tide, the Loughor estuary is extremely treacherous and you don’t want to end up becoming another statistic.
Finally as you have to cross an unstable causeway, I’d recommend wearing some suitable walking shoes or stable trainers which you don’t mind getting a little wet and sandy."
