In the Middle Ages Clifton Down was the commons of pasture for the manor of Clifton. It was also valuable farmland used by many farms in the area. In 1676 and 1686 the manor of Clifton was purchased by the Society of Merchant Venturers. During the 18th century Clifton became a fashionable summer spa, and Clifton Down was increasingly used for recreation. There were also lead mines in the 18th century, which account for the bumpy surface in the area by Upper Belgrave Road known as the Dumps. A gibbet was erected opposite the top end of Gallows Acre Lane (now known as Pembroke Road).
