On a previous visit I was told that this is a "folly" but today I realised that is [was] a shell house. It would appear that it was decorated with shells inside rather than outside.
A shell is usually a small building, of distinctive shape, and decorated with sea shells. The degree of decoration can vary, from simple lines or features, to a full wall and ceiling covering. Time consuming to make, expensive now to maintain and restore, they are always going to be a rarity.
In October 2003, Francis Street's well-established and reputable traders joined forces to form Dublin's first and foremost Antique Quarter, and to launch it they published a slick little guide to Francis Street listing its many antique shops, art galleries and restaurants.
