Masking an earlier 1696 structure, Strokestown Park, Co. Roscommon, was modified c.1740 to form a Palladian house with flanking pavilions, possibly to the designs of Richard Castle, one of Ireland’s most celebrated architects. The Library wing had major problems with dry rot, an issue which can affect many building types. Several decorative items had been affected, including historic wallpaper, and extensive repair works were required.
