The town of Castine, Maine is one of the oldest settlements in the Penobscot Bay area and has a fascinating history. It was first settled by French fur traders in 1614. It’s location at the head of the Bay near the entrance to the Penobscot River provided access to the resources of the vast Maine wilderness. This strategic location in later years led to the establishment of the Dyce Head Lighthouse to aid commerce and shipbuilding.
