The shop started in a portacabin in 1994.  By 2001 the new building was completed.  The building contained the  Entrance Hall, Mizen Cafe, washrooms  and Fastnet Hall, which was kitted out as a shop, ticket office,navigational aids simulator and 1/10 scale model of The Fastnet Rock Lighthouse. .

In 2019 Fastnet Hall was completely remodelled.  All the fittings of the first shop, ticket office and simulator were taken out.  A new,  bright, inviting retail space was created..
