Baalhoek is mostly associated with the "Baalhoekkanaal" (Baalhoek Canal), a plan for a shortcut to the harbour of Antwerp to bypass the narrows of Bath that was proposed in 1967, but finally rejected in 1998 due to the resistance of a coalition of environmentalists and farmers.
It takes its name from Broome Bridge, which crosses the canal, a place best known as where William Rowan Hamilton discovered the mathematical notion of quaternions.
In 2012, playwright Rob Inglis was awarded a £16,000 Arts Council grant to write Regent's Canal, a Folk Opera, a musical that celebrates the 200th anniversary of the digging of the canal.
