Apparently the first light on the pier here was established in 1886 but I have been able to find no mention of it. More to the point, nor has Leo Coy, who is very much the Rosslare Harbour expert. Maybe it was just a lantern on a pole?
This lighthouse was constructed when the new pier was built around 1906 ish to facilitate the larger ferries crossing to the South Wales coast and later to France. Unfortunately, the only way to get close up shots of this lighthouse is to take one of the ferries. I chose the Rosslore to Fishguard (Wales) day trip - which costs €5 on a Tuesday!
The light shows white from the harbour itself, green from a more northerly direction and red when approaching from the south east.
