This attraction is well worth a visit and the line up to gain entry. There is a fee. You can easily spend over an hour here taking pictures using the limited available light. This is a damp environment, and water may drip down from the ceiling. And do take a look at the base of the pillars - you may see carved facial features. You will also find the "Cistern Cafe" and small souvenir shop here.
Would we recommend this Attraction: Yes, at least once.
