Fort Edgecomb, built in 1808–1809, is a two-story octagonal wooden blockhouse with restored fortifications located on Davis Island in the town of Edgecomb, Lincoln County, Maine, United States. The fort was built as part of the second system of US fortifications, guarding the then-important port of Wiscasset, then one of the largest shipbuilding centers in New England. A war scare with the British over US trade with France during the Napoleonic Wars sparked the building of these forts, along with Thomas Jefferson's Embargo Act of 1807, which closed US ports and vessels to foreign trade. The fort's construction was supervised by US Army engineer Moses Porter. Although the fort was built for defense, its first use (as with most of Maine's second system forts) was to enforce the embargo. (wikipedia.org)
