The Gold Coast is one of the oldest areas in Chicago dating back to 1882 when civic leader, Potter Palmer, bought land covered by frog ponds on what later became north Lake Shore Drive and built an imposing mansion there. Land values there increased by 400 percent within a decade and this "Gold Coast" became the home of the leaders of the Chicago Four Hundred. The Latin School, one of Chicago's most prestigious private schools, is located within walking distance of all Gold Coast residences. The Gold Coast also boasts the famed Rush Street and Division Street entertainment district, which houses some of the most popular and frequented bars and restaurants. The Newberry Library, located on Washington Square Park between Clark and Dearborn has one of the most diverse collections of research in the country. Today, the housing in the Gold Coast consists of lavish mansions, graystones, brownstones and high-rises
