in 1849. He had the former St. Clare's Seminary renovated to rent out as a summer home and had a smaller brick house built for himself in 1850–1851 along "Belle Avenue" at the present-day intersection of Mountford Avenue and Belleau Street. In 1854, Bell sold a five-acre tract of land to St. Mary's Parish, whose predominantly German Catholic parishioners worshiped in East Allegheny, for a cemetery. Stonemason and engineer James Andrews bought his first section of "Nunnery Hill" in 1864 and commissioned his Heathside Cottage for the site soon thereafter. Other significant early purchasers include Robert Henderson, who had the Henderson-Metz House built around 1860. 1870–1900: Growth While wealthy residents of Allegheny established country estates on Nunnery Hill in the late 19th century, others put the hilltop area to other uses typical of the rural-urban fringe. Stone quarrying, brick-making, and coal mining occurred throughout the hill. St. Mary's laid the cornerstone for a mortuary chapel at its Nunnery Hill cemetery in 1870. After searching for several years for a "hill district" site for a municipal smallpox hospital ("pest house"), in 1883 the city of Allegheny bought a house and land on Warren Street for this purpose. Still, new private and public sector services encouraged settlement of Nunnery Hill in the 1870s and 1880s. The Twelfth Ward school district bought land for a new school on Willis Street (now Meadville Street) in 1877, which opened to students within the next several years. The city built a pumping station at Howard Street in 1882 to pump water along the present-day location of the Rising Main steps to tanks (and later a reservoir) atop Nunnery Hill. But no improvement accelerated speculation and homebuilding so much as the Nunnery Hill Incline, completed in 1888. The curved incline carried passengers from the present-day intersection of Henderson Street and Federal Street to its terminus on Meadville Street. (The old retaining wall that was built for the incline can still be seen running up the side of Henderson Street.) Other developments during the late 19th century included the founding in 1880 of a "Home for Colored Orphans," located for a few short years at the intersection of Fountain Street and Sandusky Street; demolition of the old St. Clare's Seminary in 1881 to make way for James Andrews' second and final Nunnery Hill residence, Ingleside Place; installation of a sewer system; establishment of the McNaugher Memorial United Presbyterian
