Extract from The Changing Face Of Warminster by Wilfred Middlebrook, published in 1971:
Primrose Lane runs along the top of this Weymouth Street field [on the west side of Weymouth Street] in which flows the Swan River. A pleasant, secluded lane this, linking Weymouth Street with the foot of Sambourne Road and Emwell Street, with the new Western Car Park now opening up the vista of olden Warminster as seen along the rear of High Street and George Street.
