Everytownland reads the registered freehold land and the statutory boundaries of Tailte Éireann, the national zoning, planning file and heritage records of the Department of Housing, Local Government and Heritage, and the Residential Property Price Register. A parcel is the land of a title, not an address. The owner's name is in the Land Registry of Tailte Éireann: a copy of the folio can be ordered on landdirect.ie, for a fee; this site names no owner. A price is the price recorded for a past sale, not a valuation.
