In 1917, the Union Arcade opened in downtown Pittsburgh. It was a multi-floored shopping center with office space in the upper floors. It is now known as the Union Trust building, and only the ground floor has public shopping as the rest of the building is office space.

There are many interesting features to this building. This picture is from the second floor, looking over the balcony at the entrance way with its stained glass windows, mosaic tiled ceiling, and hanging chandelier.
