The state has added a small but significant piece of land to the Colonial Pemaquid State Historic Site in Bristol.

The oceanfront parcel, just one-third of an acre and surrounded by other state-owned land, was purchased for $195,000, with help from the Maine Coast Heritage Trust and the Land for Maine's Future program. Patrick McGowan, commissioner of the Maine Department of Conservation, plans to announce the acquisition during a news conference at the site Wednesday at 11 a.m.

The Colonial Pemaquid Historic Site was once settled and farmed by Pemaquid Indians. Europeans settled the spot in 1620 as a fishing station. It is believed to be the site of the first stone fort constructed in New England.

The newly acquired property contains foundations of two Colonial houses and hearths, as well as a barrel that lined a well. Its purchase will allow more research at the site.
