The Hallock Building at Oak and Natio Parkway is the oldest standing building in Portland. Built by Absalom Hallock in 1857, the Hallock building has seen many tenants throughout the years. First occupied by Mr. Hallock, it later was used as a candy factory, a leather products company, and many others, recently it was home to Peter Corvallis Productions where I worked as a teenager. Over the years, the exterior of the Hallock building has been covered in stucco, the cast iron removed, and fallen into a bit of general disrepair.
