Cape Cod, surrounded by the Atlantic, is popular for its huge untamed beaches and inimitable lifestyle. The imposing seaside mansions at Chatham catch the imagination, as do the romantic lighthouses, the artists' cabins tucked away in the dunes around Provincetown and the sunset over the salt marshes. Cape Cod, often referred to as the "Cape", is inhabited all year round, particularly in the south, by maritime biologists, fishermen and farmers.
