Because it was under foreign control, it was suppressed in 1446, and responsibility for the site eventually passed to The Queen's College, Oxford, to whom it still belongs.

[5] The river continues beneath a bridge dated 1831, which consists of five elliptical cast-iron girders supporting plates on which the roadway is constructed.

[6] Shortly afterwards, the river is crossed by the course of another Roman road, and passes beneath Lock's Bridge to enter Bramley Training Area.

[7] The channel splits into two, and joins up again after both routes have passed under the Great Western Railway line connecting Basingstoke and Reading, which bisects the training area.

This was an Iron Age hillfort, covering 10 acres (4 ha), which has never been excavated archaeologically, and is a scheduled monument.

[1] Vyne Stream is a tributary of Bow Brook, which rises from springs in the south-easterly part of Sherborne St John.

Wey Brook, which rises from springs on both sides of the A340 road to the north-west of Sherborne St John, supplies water to watercress beds and flows eastwards to join Mill Head.

Its outflow powered a watermill, beyond which the river turns to the north and passes a sewage treatment works on the right bank.

[10] At its southern end, the lake is crossed by a three-arched bridge, constructed from red bricks with cast iron parapets in 1840.

The Manor of Sherborne St John was owned by Hugh de Port at that time, and contained three mills worth 27 shillings and sixpence (£1.37).

In addition, Vyne Stream is affected by groundwater abstraction, the impounding of water, and the presence of the invasive North American signal crayfish.
