Greystone Bridge

Greystone Bridge is a road bridge over the River Tamar, built in 1439 with later repairs. Thomas Mede, the Abbot of Tavistock, contributed significantly to the construction costs. On December 27, 1439, Bishop Lacy granted a forty-day indulgence to anyone who donated towards the bridge's erection. The bridge features roughly coursed snecked slatestone and ashlar with freestone dressings on four of its eight arches. It has five almost semi-circular arches, each spanning 7 metres, which spring from imposts 3 metres above the water level. Four of these arches have freestone dressings with arch rings, while the fifth arch to the west has a possibly 18th-century dressed stone arch.

Between the five arches on both sides are cutwaters that extend to form refuges, corbelling out at the base of the parapet above the chamfered granite moulded string. This string is mitred at the corners where it changes level. To the west, there is a four-centred dressed stone arch over the flood plain, and two similar arches on the east with a small cutwater between, which continues up to form a refuge. The arches over the flood plain may have been rebuilt, and the moulded string above loses its mitred corners where it changes level. Henderson's description in 1928 only noted two flood arches. The roadway over the bridge, which was formerly paved, is 3 metres wide, and the parapets are splayed on the east and west sides.

The approaches to the bridge were once much steeper and were modified for the stagecoach route between Tavistock and Launceston. The bridge can be compared to Horse Bridge to the south, built in 1437, likely by the same architect. The estate of the Abbots of Tavistock, known as Endsleigh, extended down to the river between Greystone Bridge and Horse Bridge.
