Allegheny City ( 1788  1907 ) was a Pennsylvania municipality located on the north side of the junction of the Allegheny and Ohio Rivers , across from downtown Pittsburgh . It was annexed by Pittsburgh in 1907. The area today is known as the North Side of Pittsburgh, and its waterfront district, along the Allegheny and Ohio Rivers, as the North Shore . Prior to the 1850s, this area was largely farmland, but was subdivided into residential lots, first for the growing German population and later for the Croats . It was commonly referred to as "Deutschtown". A massive urban redevelopment project in the 1960s demolished the core of historic Allegheny City, leaving only the Commons and its surrounding neighborhoods to evoke the area's past. Fortunately the Carnegie Library, Old Post Office Building and the Buhl Planeterium buildings were not demolished. Major portions of the neighborhoods of Allegheny West, Manchester, Mexican War Streets, Central Northside, and East Allegheny are listed on the National Register of Historic Places . The area of Allegheny City included the present Pittsburgh neighborhoods of Allegheny West , Brighton Heights , East Allegheny , Fineview , Manchester , Marshall, Mexican War Streets , Mt. Troy, Observatory Hill, Perry North , Perry South , Perrysville, Riverview, Spring Garden , Spring Hill , Summer Hill , and Troy Hill .
