The Greenbank Mill is a living museum and historic site in Wilmington, Delaware. It features and preserves a 18th century mill.

The Greenbank Mill traces its roots back to 1677 with the Swedish immigrants that moved to the area. They built a mill along the Red Clay Creek upon arrival, but the current mill was only completed in 1790s. The site operated until 1969 and even expanded into wool processing some time during the 19th century.

Today, the Greenbank Mill offers Delaware’s early history through its historic structures. Most of the mill’s original elements are still intact and with the addition of the Philips Farm property, more information is offered to the public. The site also hosts regular events and activities.
