Fáilte Towers was an RTÉ reality TV show that was broadcast as a one off during August 2008. The concept of the show involves thirteen celebrities running a hotel for sixteen days and nights in order to win money for their designated charities. The show format was not repeated nor was it exported or resold. The name is a play on the BBC sitcom Fawlty Towers: and the word Fáilte meaning "welcome" in Irish. The hotel used in the series is Bellingham Castle in Castlebellingham, County Louth. The show is presented by Aidan Power and Baz Ashmawy and the judges are Bibi Baskin, Dublin restaurateur Derry Clarke and Castle Leslie hotelier Sammy Leslie. Each night the public are invited to vote for the contestant they would like to stay in the show. At the end of the show one of the contestants must "check out". The presenters tell each of the contestants individually if they are "safe" and if so are ordered "back to work". The three remaining contestants are then marched into the Oliver Plunkett Suite to face the judges, one of whom sends one of the contestants back to work before all three cast their votes on which of the remaining two must leave the show. The evicted celebrity is then interviewed by the presenters, with best bits shown as well. Created by Adare Productions, it was available to watch online on the RTÉ Player for up to two weeks after being broadcast. John Creedon won on 17 August.
