If coming by car, use the car park behind St Martin's Walk shopping mall (car park entrance via Mill Lane) and use the footpath at the west end of the car park to take you south to Church Street. Turn right (i.e. to the west) and continue past North Street....
If coming on foot, find the junction of North Street and Church Street and turn west along Church Street....
....on the left after a few houses, there is a small car park (usually full in the evening) belonging to the United Reformed Church. The Follett Hall is the building on the right as you enter this car park.
