Maine became the 23rd state to be admitted into the Union, as part of the Missouri Compromise on March 15, 1820. Pemaquid Point Light is located in New Harbor, and marks the entrance to Muscongus Bay and Johns Bay. Since the beginning of ship activity in the area, a shoal created hazardous navigation conditions, causing many shipwrecks. As maritime trade increased in the area, so did the need for a lighthouse. In 1826, Congress appropriated funds to build a lighthouse at Pemaquid Point. 471 0 0 0 16 9. Lobster shacks, waves crashing against rocky outcroppings, pine trees, and rugged bluffs—Maine is New England’s crowning gem.
