Rothe House is considered to be nationally significant because of the wide range of original post-medieval features which survive in good condition in Ireland. The property, an important element of Kilkenny's heritage, is owned by the Kilkenny Archaeological Society and houses some of the society's collection of artefacts relating to Kilkenny City, County and Ireland.
The garden to the rear of the house has been reconstructed to reflect a typical 17th-century garden. The burgage plot on which Rothe House was built survives intact one of a few in such an unaltered state. Kilkenny's medieval city wall forms part of the curtilage of the Rothe House complex.
