Cape Cod, is one of the most historic areas in the continental United States as it was a key location for the original 13 colonies and even claimed to have been visited by early nordic explorers like Leif Eiriksson. The area has transformed from its early days as a whaling and trading hub into a resort destination for the affluent. Since 1914 the Cape Cod canal has separated the cape from the mainland. The cape can be divided into four main areas: Upper Cape, Mid-Cape, Lower Cape, and Outer-Cape which include cities such as Mashpee, Dennis, Chatham, and Provincetown respectively. As it has been a major nautical area for centuries the coast is also dotted with lighthouses throughout the cape.
