Place & story
The earlier castle
A castle once occupied a rise in Slevoir with views north over Lough Derg. The archaeological account reproduced in the Heritage Council's waterway study identifies James Butler of Tullow, County Carlow, as its proprietor in 1640. By the Civil Survey of 1654–56 it was already demolished. A field inspection in March 1995 found no remains visible at ground level. [2]
Residents before the rebuilding
The University of Galway's estate research records R. Monsell at Slevoir in 1837. At the time of Griffith's Valuation, the Reverend Francis Synge occupied the property under the representatives of Mr Steele, with the buildings valued at £34. These records establish a sequence of nineteenth-century occupation before the construction of the present Italianate house. [3]
McCurdy’s lakeside tower
John McCurdy designed the present Slevoir House for Lieutenant Colonel J. F. Hickey around 1870. Its entrance rises through a four-stage granite tower, while a lower wing extends beside the main two-storey block. Red marble columns flank the doorway, and a courtyard of stable buildings stands to the south. The 2004 architectural survey recorded replacement windows and doors but found much of the exterior intact. The tower remains the building's most conspicuous feature when seen across the lake. [4]
