Hobson's Conduit is a watercourse that was built from 1610 to 1614 by Thomas Hobson to bring fresh water into the city of Cambridge, England from springs at Nine Wells, a Local Nature Reserve (52.166°N 0.1349°E (Hobson Conduit (spring at Nine Wells))), near the village of Great Shelford. It is now a Scheduled Ancient Monument and historical relic. What remains of the conduit flows beside Trumpington Street and past Brookside, where it is at its widest. At the corner of Lensfield Road stands an octagonal monument to Hobson, which once formed part of the market square fountain, and was moved to this location in 1856, after a fire in the Market. The flow of water runs under Lensfield Road, and subsequently runs along both sides of Trumpington Street in broad gutters towards Peterhouse and St Catharine's College, and also St Andrew's Street.
