city, residential suburb 6 miles (10 km) east of downtown Cleveland, Cuyahoga county, northeastern Ohio, U.S. Located at the extreme western edge of the Appalachian Plateau, the area was home to Erie and Seneca tribes before being settled in the 1820s by pioneer farmers. At the end of the 19th century it was developed as one of Cleveland's first garden suburbs, catering to the city's elite. Incorporated as a village in 1903, Cleveland Heights remained a rural area until it became a city in 1921. It is zoned only for homes, offices, and retail businesses and has no industry, although several large corporations have their headquarters there. Since the 1970s it has been noted for the racial integration of its neighbourhoods and for the diversity of its residential architecture. The city's Cain Park has an outdoor summer theatre in a natural amphitheatre setting; Forest Hill Park is a former summer estate of the Rockefeller family. Pop. (2000) 49,958; (2005 est.) 48,029.
