East Cleveland is home to General Electric's historic Nela Park, the world's first industrial park. Nela Park, which was added to the National Register of Historic Places in 1975, continues to operate today as the functional headquarters for GE Lighting and is the city's second largest employer. Huron Hospital, a satellite hospital of the Cleveland Clinic, was the city's largest employer. Huron Hospital was a notable health care facility, being the only Level-II trauma center between Cleveland's MetroHealth Medical Center, located on West 25th Street, and Hillcrest Hospital, located in Mayfield Heights. Huron Hospital closed in early spring of 2011.
