Set in the scenic Don Valley, Todmorden Mills Heritage Site is a complex of historic buildings which were once part of the small industrial community of Todmorden.

Today the site consists of two historic millers' homes dating from the early 19th century, the Brewery building and the recently renovated Papermill Theatre and Gallery. Adjoining the site is a 9.2 hectare wildflower preserve with walking trails exploring a number of natural habitats, including upland and bottomland forests, dry and wet meadows, swamp lands and a pond. Todmorden Mills Heritage Site is one of 10 historic museums operated by the City of Toronto. Toronto's Historic Sites engage visitors, inspire passion, challenge ideas and connect the past to the present.
