What is oldest building in maine?

The oldest building in Maine is the fort and trading post at Pemaquid Point, located in Bristol. It was first established by English fishermen in the early 1600s, and the fort was built in 1692 to protect the trading post and nearby settlements from French and Native American raids. The fort changed hands several times between the English and French during the colonial period, and was eventually abandoned and left to decay. Today, the site is a state historic site and offers a glimpse into Maine's early colonial history.
