Inishtrahull Lighthouse, Ocean navigation lighthouse on Inishtrahull Island, County Donegal, Ireland
Inishtrahull Lighthouse is a white concrete tower standing on Ireland's northernmost island and helps ships navigate the Atlantic Ocean. The structure now operates automatically and runs on solar power.
The first lighthouse structure was built in 1812 to guide British naval vessels and began operating in 1813. This early installation was part of the critical maritime infrastructure of the early 1800s.
The lighthouse symbolizes Ireland's connection to the sea and marks a vital reference point for ships crossing the Atlantic. This role has made it part of the country's maritime identity.
The tower itself is not open to visitors, but the island can be explored on foot. The best time to visit is during calm weather and stable sea conditions.
An advanced fog signal station was installed in 1905 using compressed air to produce consistent directional signals. This technology proved valuable for ships when fog reduced the visibility of the light beam.
