Hook Head lighthouse on the Wexford Coast
Blindingly white on a summers day with all the whitewash around.
There are a bunch of cottages (second pic) just away from the lighthouse which now house a cafe/shop and admissions desk.
It's thought to be one of the oldest operational lighthouses in the world. It dates from the early 13th century and is a unique example of an almost intact medieval lighthouse though it doesn't look it a first sight.
The tower was constructed of local limestone and the original building survives almost intact at just under 37m high. It consists of two tiers linked by a mural stairway of 115 steps. The upper tier, originally supported the coal beacon, which in modern times was replaced by a lantern.
