The Cedar Glen Apartments is a historic apartment building located in the University Circle neighborhood of Cleveland, Ohio, in the United States. Designed by prominent local architect Samuel H. Weis and completed in 1927, the building originally contained luxury apartments and served as a gateway to the more exclusive neighborhood of Cleveland Heights, on whose border the building is located. Threatened with demolition in 1992, the building was purchased by new owners and converted into condominiums. The structure was added to the National Register of Historic Places on June 17, 1994. Development of Cedar Glen Geography of Cedar Glen and the Quarry Railroad The city of Cleveland lies on the shore of Lake Erie on the Erie Plain. Just a few miles inland is the Portage Escarpment, which separates the Erie Plain from the Appalachian Plateau. The Portage Escarpment also defines the political geography of Cleveland and its eastern suburbs, and acts as both the legal and natural boundary between Cleveland and the city of Cleveland Heights, Ohio. In part, two ravines provided natural access to the heights atop the escarpment. One was the Doan Brook ravine, which today is encompassed by Ambler Park. The other was Cedar Brook ravine, more commonly referred to as Cedar Glen. Cedar Brook emptied into Doan Brook at the base of the hill. Nearby, a natural mineral spring known as Blue Rock Springs bubbled up from the ground. From the beginning of white settlement of the area until about 1890, the area atop the escarpment (which would later become East Cleveland Township in 1847 and Cleveland Heights in 1901) was only very sparsely settled. Scattered on the edge of the escarpment were dairies, farms, orchards, and vineyards. For much of this period, only a narrow, ill-repaired dirt road ran through Cedar Glen. Beginning in the early 1800s, several Euclid bluestone quarries operated atop the escarpment. In 1834, a narrow-gauge railway, the Quarry Railroad, was built from Public Square to E. 101st Street along Chester Avenue, and then along what is now Martin Luther King, Jr. Avenue to Cedar Glen Parkway and up Cedar Hill to the quarries above. The railroad failed in 1849. Early developments atop Cedar Glen In 1869, a group of Cleveland businessmen pooled their resources to create the Lake View Cemetery straddling the Cleveland-Cleveland Heights border about northwest of Cedar Glen. In 1873, John D. Rockefeller purchased of land (bounded by
