Fort Pentagouet (Castine, Maine)

Castine · Maine · King William's War, Queen Anne's War

Quick BriefFort Pentagouet was erected in 1625 by Charles de Saint-Étienne de la Tour and seized by Plymouth Colony in 1629, becoming a focal point of European imperial rivalry on the Penobscot River. The fort served as capital of Acadia from 1670 to 1674 and played a central role in King William's War when Saint-Castin's settlement was plundered in 1688 and retaliated with a raid on Pemaquid in August 1689.

History & Significance

Positioned at the mouth of the Penobscot River estuary, the site commanded a lucrative trade in furs and timber and served as a major transportation route into the interior. Charles de Saint-Étienne de la Tour erected the original fort in 1625, but English colonists from Plymouth Colony seized it in 1629.

From 1635 to 1654, Charles de Menou d'Aulnay de Charnisay maintained French commercial interests there after Governor Isaac de Razilly retook the village. When Acadia was returned to France in 1670, Fort Pentagouet became the capital under Governors Hector d'Andigné de Grandfontaine (1670–73) and Jacques de Chambly (1673-74).

During the Franco-Dutch War in 1674, Dutch captain Jurriaen Aernoutsz captured the port and destroyed most of the fort by turning its own cannon on its walls. Saint-Castin retook the fort in 1676 and maintained French authority from his nearby trading post until 1700. The Pentagoet Archaeological District was designated a National Historic Landmark in 1993.
