Endicott Rock is a state park located on the shore of Lake Winnipesaukee in the Weirs Beach village of Laconia, New Hampshire. Its principal attraction is a large rock originally in the lake that was incised with lettering in 1652 by surveyors for the Massachusetts Bay Colony. The rock provides definitive evidence of one of the earliest incursions of Europeans into the area.
For many years the rock's existence was unknown, until it was rediscovered in the 19th century when the Weirs Channel was dredged. The state then undertook to protect the rock from the elements, building a pavilion over it and stabilizing cracks in the rock with iron fittings. The markings on the rock include "IOHN ENDICUT GOV", a reference to John Endecott, who was then governor of the Massachusetts Bay Colony, and the initials of the surveyors.
