The Gold Coast Historic District is a historic district in Chicago, Illinois. Part of Chicago's Near North Side community area, it is roughly bounded by North Avenue, Lake Shore Drive, Oak Street, and Clark Street.
The Gold Coast neighborhood grew in the wake of the Great Chicago Fire. In 1882, millionaire Potter Palmer moved to the area from the Prairie Avenue neighborhood on the city's south side. He filled in a swampy area which later became Lake Shore Drive, and built the Palmer Mansion, a forty-two room castle-like structure designed by Henry Ives Cobb and Charles Sumner Frost.
