In 1684 there were around 250 people in the township, occupying 50 houses. The town became famous for manufacturing blankets and by 1811 the Blanket Hall was built for trade in the town's primary manufacture. It was replaced by a second hall erected in 1839, on Blanket Hall Street in the town centre. Elizabeth Gaskell's biography of Charlotte Brontë in 1857 described the inhabitants of Heckmondwike as "a chapel-going people, very critical of their sermons, tyrannical to their ministers and violent radicals".
