It is a modest construction, five or six courses of mortared rubble limestone rising to a curving back, topped with a round-profile cement capping and approached by a single flat limestone slab that serves as a step. Nothing about it announces itself. It simply sits in open pasture, facing south towards the water.

The seat is thought to date from the eighteenth or nineteenth century, and the first edition Ordnance Survey six-inch map confirms that the surrounding land formed part of the Portland House demesne. Designed landscape features of this kind were a common expression of Georgian and Regency estate culture, where landowners would commission seats, follies, and prospect points to frame particular views across their property. The idea was less about utility than about curating an experience of the landscape, turning a walk on the estate into something that could be paused and contemplated from a specific, considered vantage point. This one was positioned with care. Lough Derg, the southernmost of the Shannon lakes and one of the largest in Ireland, spreads out below, and the elevation of the hill would have made the view considerable even before the surrounding trees, if there were any, had been planted or cleared to suit it.
