A summer destination for more than 100 years, Castine is a well-preserved seaside village rich in history. The French established a trading post here in 1613, naming the area Pentagoet. A year later Captain John Smith claimed the area for the British. The French regained control of the peninsula with the 1667 Breda Treaty, and Jean Vincent d'Abbadie de St. Castin obtained a land grant in the Pentagoet area, which would later bear his name. Castine's strategic position on Penobscot Bay and its importance as a trading post meant there were many battles for control until 1815. In the 19th century Castine was an important port for trading ships and fishing vessels. Larger ships, the Civil War, and the advent of train travel brought its prominence as a port to an end, but by the late 1800s some of the nation's wealthier citizens had discovered Castine as a pleasant summer retreat.
