Great Shelford

I have long wanted to do this complete walk, from the source of Hobson's Conduit to the city centre, having walked parts of various sections over the years.  Hobson's Conduit, also called Hobson's Brook, is a watercourse that was built from 1610 to 1614 to bring fresh water into the city of Cambridge from the freshwater chalk springs at Nine Wells; the scheme was financed by Cambridge University, but Thomas Hobson, a local businessman, was involved in the construction and set up a maintenance endowment for the waterway which is now named after him.  

Nine Wells is a nature reserve close to Addenbrooke's Hospital; there are four springs here and a monument, one of two, to the conduit.  Hobson's Brook runs past the hospital and biomedical campus; there is a slight diversion for walkers away from the brook due to ongoing building work at the new Cambridge South railway station, but I soon re-join the path and follow it with the Hobson Park Bird Reserve on one side and the edge of Great Kneighton village on the other.  I then cross the Cambridgeshire Guided Busway track before walking through more green space to reach Long Road (A1134); after this, the waterway reverts to its original name of Vicar's Brook as I cross over and onto Darien Meadow.

At the end of the meadow, the man-made channel of Hobson's Brook branches off from Vicar's Brook - there is a small bridge to cross here (obviously) and the two run parallel for a while enclosing a stretch of common ground, now used for allotments (the Empty Common Community Garden), emerging at the junction of Brooklands Avenue and Trumpington Road.  The waterway passes the west side of the Cambridge University Botanical Gardens (it supplies water to the small lake here) before reaching the conduit head at Lensfield Road, where there is the second monument to Hobson and the conduit - the original Market Fountain was moved here in 1856.  

The flow of water was divided into four separate branches from here for different uses, but only one branch remains - the Trumpington Street branch, which fed Peterhouse and Pembroke Colleges, as well as the original Addenbrooke's Hospital.  I follow this, seeing the deep channels known as runnels at the side of the road that did this, and then divert to the Market Square; the original fountain was partly moved to form the monument in Lensfield Road and soon after a Gothic Revival gabled fountain was erected, but most of this Victorian fountain was pulled down in 1953.

It has been a very interesting 4.4-mile walk with great views in places (see captions on photos).Read more
