Coos County is a place with a unique and storied history. The county was established in 1805, meaning it has already celebrated over two centuries of life. Its settlers were intrepid individuals filled with courage who braved the untamed wilderness and inhabited this area, filled with the Abenaki tribes, trees, and wild animals. Nowadays, Coös County makes up 20% of New Hampshire's land area and covers 1,800 square miles - but, despite its large size compared to other counties in the state, only 2.5% of New Hampshire's population lives here. Bordered by Canada to the north, Vermont to the west, and Maine to the east, the county seat is located in Lancaster. While Coös County remains a haven for nature lovers and those looking for peaceful surroundings, its people still carry forward their spirit of adventure since their ancestors first encountered these lands over 200 years ago.
