The cathedral is beautiful well worth the entry fee of Euros2.00 per person. My wife and I also had the pleasure of a private tour with a retired priest of the diocese who happened to be there at the time we entered - a charming man.
However, you should be warned if you are British and the lady at the entry desk discovers this you will be given a ranting demand for the "return" of Gibraltar to Spain and the "return" of the Falklands/Malvinas to Argentina. A very nasty experience.
