In [medieval] times the manor was the nucleus of English rural life. It was an administrative unit of an extensive area of land. The whole of it was owned originally by the lord of the manor. He lived in the big house called the manor house. Attached to it were many acres of grassland and woodlands called the park. These were the "demesne lands" which were for the personal use of the lord of the manor. Dotted all round were the enclosed homes and land occupied by the "tenants of the manor."
