In English common law, real property, real estate, realty, or immovable property is land which is the property of some person and all structures (also called improvements or fixtures) integrated with or affixed to the land, including crops, buildings, machinery, wells, dams, ponds, mines, canals, and roads, among other things. The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property was, and continues to be, all property that is not real property.
