Portland Basin, also known as New Wharf, is the terminus of the Ashton Canal where it meets the northern end of the Peak Forest Canal. There is also a short branch to Dukinfield.
The basin was used originally for loading coal bound for Manchester. A four storey brick warehouse with two central loading bays opened in 1834. It was powered by a waterwheel.
The masonry arch bridge carrying the Ashton Canal towpath over the Peak Forest Canal was built in 1835. It has a single ring of voussoirs with a keystone, a deck of stone setts and stone flag parapets.
The warehouse was damaged badly by a fire in 1973, although the ground floor with its original cast iron columns and waterwheel survived. It was rebuilt and later enlarged, re-opening as the Portland Basin Museum on 28th April 1999.
In 2000, a small independent marina opened adjacent to the basin. A canal festival takes place at the basin every year for three days in July.
