Seen from the bridge across Upper Lough Erne to Inisherk Island, this is the hexagonal summer house at Crom Castle, County Fermanagh. According to an 1830s Ordnance Survey map, it stands on the site of an older schoolhouse, but that in turn may have been adapted from an 18th century building, the two-storey hexagonal building designed by Sir Edward Lovett Pearce ‘For Mr Creighton to be built on a Sunk Island in Lough Hern’, of which an undated drawing survives. In its present incarnation, the summer house dates from the second half of the 19th century.
