Heritage Open Day: Come and explore the refined Georgian craftsmanship of this church built for the expanding merchant community of Lancaster. Consecrated in 1755, with a distinctive Neoclassical tower and spire added in 1784, St John’s was built by and for the expanding merchant community of Lancaster, at a time when Trans-Atlantic trade - including trade in enslaved people - brought prosperity and growth to the city. It was built near to the Lune-side docks, which connected Lancaster to the Atlantic and thence to Africa, the Americas and the Caribbean, and known locally as ‘t’owd fish church’ for its fish-shaped weathervane and maritime associations.
