Building MPM822 - BOILER SHOP WEST (BUILDING NUMBER 1/84) AND BOLLARDS TO NORTH WEST AND NORTH EAST CORNERS

Hemp tarring house, now offices and store. Built 1747, considerably altered subsequently, particularly 20th century.

The earliest part of the ropery, converted from manual to horse power c1774; hemp was passed from the laying house for tarring before being returned to the spinning house. Although much altered, this is the oldest naval ropeyard building, and part of one of the largest integrated groups of C18 industrial buildings in the country. This is the only part of the mid C 18 ropery at Portsmouth to survive both the 1760 and 1770 fires.
