built in 1899 to serve the George Woofindin almshouses, arranged in a crescent on the north side of the river. The river then enters a section of culvert, to emerge on the south side of Eccleshall Road, and weaves its way between housing to reach Sharrow Vale dam and snuff mill. The main building, dating from 1737 onwards, straddles the river, with a newer building dating from 1880 to the north, containing the original machinery which was still in use in 2004. At the eastern end of the buildings is a bridge dating from the late 18th century. The river then runs parallel to Ecclesall Road along the north-western edge of Sheffield General Cemetery. The main gateway, built in Greek Revival style by the Sheffield architect Samuel Worth in 1836, incorporates a lodge on either side, and the whole structure is built on an elongated bridge across the river. After passing under Pear Street and Summerfield Street, it enters a site which was Ward's Brewery until it closed in 1999. It has been redeveloped as housing, although the original entrance arch has been retained. The river then enters the Waitrose culvert, which carries it under Harrow Street and a Waitrose supermarket. It appears again near the former Sheffield Union Banking Co building, which in 2021 was the Baan Thai Restaurant, before the St Marys Gate culvert takes it under London Road and the A61 St Mary's Gate. There is a short exposed section by the Theatre Deli car park and the Eyre Street culvert then passes under Eyre Street and the Decathlon sports shop, before the river re-emerges on the north side of Mary Street. It flows under Matilda Street Bridge, through the new Matilda Street Pocket Park and behind the BBC offices on Shoreham Street, before entering the Shoreham Street culvert beneath Leadmill Road and the A61 road. It surfaces briefly to run along the back edge of Sheffield Station car park, and enters the station culvert, which joins the culvert carrying the River Sheaf beneath the station platforms. The junction is beneath platform 5A, where there is a wooden access cover. Physical modification The river channel has been heavily modified over centuries. This has included the construction of dams to impound water for milling and metal working. The earliest mentions are of Shepherd Wheel, possibly in 1566 and certainly in 1584, while Mayfield corn mill on Mayfield Brook
