Rossroe The lookout post no. 56 is located close to Killary Harbour on the Rossroe Peninsula. Today, the building is surrounded by a stone wall and houses a transmission station for maritime radio services. Elements of the rusty Bibroch shipwreck were adapted for the light projection.
In addition, the registration number of the post was integrated into the light design. The wreck of the MV Bibroch lay next to a pier close to Letterfrack. The ship was a Clyde Puffer built in 1957, which had been out of service in Letterfrack since 2002.
