The Tenantry Column
Entirely amazing this, and a real sign of how the ruling classes were once perceived by those 'below' them.
The Tenantry Column was raised in 1816. It was paid for by the tenants of the 2nd Duke of Northumberland, who had kindly reduced their rents during the recession which followed the Napoleonic Wars.
Local legend has it that, having seen what they could afford to do with reduced rents, the duke promptly raised them again. Although this is a good tale, it's not actually true.
The column stands on a mound (perhaps the original Norman mound of Alnwick's first 'motte and bailey' castle?) just outside the Bongate Tower. You can't miss it as you drive in from the A1.
