Blackrock Light, Mayo

Not to be confused with Blackrock Light in Sligo, this baby is situated about 12 miles west of Blacksod, out into the wild Atlantic.
On heading back from Blacksod towards Belmullet, take the first turn to the left, about 300 metres down the road. Another 300 metres takes you to the brow of the hill where this a car park below some kind of sculpture park. There are a number of islands out there - Blackrock is the one that looks like a volcano.Also built in 1864, there are much better photos here from people who have access to helicopters (unfortunately I left mine at home)
