The new 98-bed Natrona Heights hospital was dedicated on May 24, 1919. The three-story, brick and terra cotta structure remains standing today, at the center of what is now a much larger Allegheny Valley Hospital. In the century that has passed since the third AVH opened, the hospital has added to that original foundation, building a nurses wing in 1928, a north wing in 1943, a $2 million south wing in 1958, a laboratory in 1974, and a four-level, $26.5 million addition in 1983 that houses AVH's emergency department, radiology, and other units.
