Galley Head Lighthouse, Maritime lighthouse in County Cork, Ireland.

Galley Head Lighthouse is a white cylindrical tower located at the southern edge of Dundeady Island on Ireland's South Coast. The structure rises roughly 21 meters above the rocky coastline, standing as a tall marker visible from the sea and surrounding land.

The lighthouse began operations in 1878 using coal gas burners that produced flashes at regular intervals to guide passing vessels. It became an important navigation point on shipping routes along Ireland's South Coast and remained in service through major maritime developments.

The light shows an unusual landward arc, said to have been added so the Sultan of Turkey could see it from Castle Freke at Rosscarbery during his visit. The abandoned Gothic ruin of Castle Freke, given up in 1952, is visible from Galley Head. The station also appears in the music video for "To The Lighthouse" by Patrick Wolf.

The site sits on a rocky island with paths leading from the cliffs to the tower that can be uneven and exposed to wind. Visitors should prepare for changeable weather and wear sturdy footwear and protective clothing.
