BRISTOL — Archaeologists will be excavating part of a state historic site in Maine to try to uncover artifacts related to British Colonial forts.

The Maine Department of Agriculture, Conservation and Forestry says the digging will begin Monday and last until Aug. 10 at Colonial Pemaquid State Historic Site. Three British Colonial forts were built on the site between the 1670s and the 1720s.

Two of the forts were destroyed by the French and the other fell into disrepair before being destroyed by local colonists. There’s a replica of one of the forts on the site today that was built in the early 1900s.

The conservation department says this year’s dig will build on an effort from last year. Last year’s dig uncovered a piece of a centuries-old cannon and other items.
