The old cattle market was where the bus station is now situated, and moved from that site back in the 1980s as part of the town centre development. It moved initially to Caxton Hill.
As a schoolgirl, I would travel over from Enfield to see the monthly market for horses. Often at the weekly cattle markets a cow would escape and bring the town to a standstill!
Maidenhead Street was a two-way street then, and it would be closed on Saturdays, probably because it was market day.
