Statement of Significance (as of designation - November 7, 1973):
Constructed 1838-1840, this is the only extant fortification of the Aroostook "War" (1838-1839), the conflict that climaxed the Northeast border disputes with Great Britain following the War of 1812. The controversy over the border began with the Treaty of Paris (1783) and was finally resolved by the Webster-Ashburton Treaty, signed in Washington in 1842. With the boundary settled, the fort was abandoned.

Condition:
The roof has been restored but there are still some moderately significant timber-framing issues to address.

The roof was restored and the dormers (missing since the 1920s) were reconstructed. New stairs were installed to alleviate water "splashing" issues. New adjacent property may be acquired this year.

Recommendation/Change since last report:
Additional interpretation (such as a walking tour brochure) is needed to improve the visitor experience and provide information on the history and significance of this historic site.
