In 1889, Frank Lloyd Wright and his wife settled in Oak Park. He built many homes and the Unity Temple, his own church, in the village, before he left in 1911 to settle in Wisconsin. Oak Park attracts architecture buffs and others to view the many Wright-designed homes found in the village, alongside homes reflecting other architectural styles. The largest collection of Wright-designed residential properties in the world is in Oak Park. A distinct focus on historic preservation of important architectural styles began in the 1970s and continues, with many buildings marked as historically significant, and so far, three historic districts defined. Other attractions include Ernest Hemingway's birthplace home and his boyhood home, the Ernest Hemingway Museum, the three Oak Park homes of writer and Tarzan creator Edgar Rice Burroughs, Wright's Unity Temple, Pleasant Home, and the Oak Park-River Forest Historical Society.
