The Katahdin Iron Works is a state historic site in Brownville, Maine. It preserves the site of an old iron works operation.

Established around the mid-1800s, the Katahdin Iron Works is an old company that maximized the limonite gossan discovered in the Ore Mountain located nearby. Sadly, its operation exhausted the local forests come 1881, so operations moved to Nova Scotia by the end of the decade. What remains of the old Katahdin Iron Works site is the blast furnace and one of its beehive charcoal kilns.

The thing about the Katahdin Iron Works is that it is an excellent addition to trips in the area, as it is located by the National Natural Landmark Gulf Hagas and ?The Hermitage?.
