This was a very tall building when it opened in 1892. It’s certainly stretching a point to call this a skyscraper, yet it is in some ways the seed of all subsequent skyscrapers in Pittsburgh. This was the first building in Pittsburgh, and one of the first in the world, built with steel-cage construction, which makes practically indefinite height possible. Below we see the Conestoga Building with a couple of its great-grandchildren behind it: One PPG Place and Fifth Avenue Place.
