Chatham is a small town and one of the oldest towns in Cape Cod. It is a peninsula with beautiful islands and beaches, and the sky is prone to moodiness, so you might see cloudy horizons and spectacular sunrises. The first settlers arrived here in 1656 and their legacy can still be seen in the quaint mills and houses dotting the landscape. The town's best known attraction is Chatham Lighthouse (Twin Lights) built in 1808 under the direction of President Thomas Jefferson. It is also equally famous for Monomoy National Wildlife Refuge, a haven for migratory birds and aquatic species. Tourists can also walk along Main Street to discover a beautiful coastal town with a whimsical mix of Colonial and modern architecture. Visit museums to learn about the town's history or simply walk on the sandy shore barefoot.
