What did St. John Street Turnpike green plaque do at Spa Green Estate?

The Story

# St. John Street Turnpike Green Plaque Standing here at Spa Green Estate, you're standing at the precise point where one of London's most essential infrastructure projects began its transformation of the city's northern approaches. Between 1746 and 1830, the St. John Street Turnpike operated from this very spot, serving as the toll collection point that funded the improvement and maintenance of the road stretching north from Smithfield—one of the capital's most critical arteries for commerce, livestock, and travellers heading to Scotland. Here, tollkeepers collected fees from coaches, carts, and drovers, their work enabling the systematic upkeep of a road that had been little better than mud and ruts before the turnpike's establishment. This humble gatehouse became a vital economic junction where London's growth met its ambitions: without the revenue collected at this threshold, the road's transformation into a modern thoroughfare would have been impossible, making this spot the beating heart of Islington's connection to the wider world during the Georgian era.
