We're at the Brentford Canal Festival today, and there's no better place to think about just how much this stretch of water once mattered.
When the Grand Junction Canal reached Brentford in 1805, it cut around 60 miles off the journey between Birmingham and London, bypassing the unreliable upper reaches of the Thames entirely. Brentford became the point where everything changed hands. Large Thames lighters couldn't navigate the narrower inland canals, so cargoes were unloaded and reloaded onto narrowboats at the wharf: timber, coal, grain, steel, and stranger things besides.
One of our favourites: barrels of lime juice imported from the West Indies were warehoused here before travelling up the canal to Rose's factory in Hertfordshire. That trade ran until 1981.
The town also had a Boatmen's Institute, built in 1904–05 by the City Mission, with a school for canal children temporarily ashore and a maternity unit for boatwomen on the upper floor.
Our volunteers are here today. Come and find our stall for a chat about London's waterways, and find out more about the London Canal Museum in King's Cross.
