This infrared photograph of the Poolbeg Lighthouse (in Irish: Teach Solais an Phoill Bhig ) was taken on a sunny summer day at the end of the pier known as the Great South Wall.

The lighthouse, which is still in use, was first built in 1767 and rebuilt into its present form in 1820. It is situated at the mouth of the river Liffey and can be reached by a 30-minute walk along the wall from Ringsend or Sandymount in Dublin.

The large cog wheel on the left of the photograph is part of a now-disused crane. The Canon EOS camera was converted for infrared by removing the UV/IR Cut Filter. This results in very unusual and striking images and is particularly interesting for landscape and architectural photography.
