Cullenstown [1] is a townland and small village located on the south coast of County Wexford, in Ireland. A small beach, Cullenstown Strand, is located nearby.[2] It is about 25 km by road from Wexford town.
Cullenstown is home to the "shell cottage" (also known as "cliff cottage"), a 19th century thatched farmhouse which was decorated with shells by Kevin Ffrench.[3] The house took over 30 years to decorate.[4] The area also contains a Gaelic handball alley,[5] a pub, and a number of holiday homes.
