One of the architectural wonders of Ireland is also one of its greatest mysteries: the forecourt of Curraghmore, County Waterford. This stupendous space, in which matching blocks of stables and offices face each other across an arena, leads up to the main house which has its own, more modestly proportioned wings. Linking the two sections are quadrants accommodating pedimented niches and entablatured doorcases, all executed in crisp limestone. Who was the architect responsible for the mise-en-scène? Both Francis Bindon and John Roberts have been proposed, but to date no one has been able to say for certain: it remains a mystery.
