Warner and Swasey Observatory, Former astronomical observatory in East Cleveland, United States
The Warner and Swasey Observatory stands on a high knoll at 270 feet above Lake Erie with two copper-domed structures for astronomical research.
The facility, established by precision instrument makers Worcester Warner and Ambrose Swasey, operated from 1920 until 1980 with advanced telescopes for astronomical studies.
The observatory conducted research that proved the Milky Way was a spiral galaxy and discovered the concentration of red giant stars near its center.
The original 9.5-inch refracting telescope from the observatory continues operation atop Case Western Reserve University's Albert W. Smith Building since 1982.
The observatory relocated its 24-inch Burrell Schmidt telescope to Nassau Station in Geauga County due to increasing light pollution from Cleveland's urban growth.
