There's a short list of "signature" buildings in Scranton-- the federal building, the courthouse, Oppenheim's, city hall, the Scranton Electric building...
If I had to pick one, I'd say this is it-- the train station at the end of the Central Scranton Expressway, the gateway to the city.
The building was constructed in 1908, and it's now a Radisson hotel.
It is spectacular at night and during the day. You can imagine what it was like when rail service was at its peak-- a bustling passenger station on the first floor, with offices above. This building came very close to meeting the wrecking ball back in the 80's, and that would have been a tragedy.
Above is the stained glass ceiling over the lobby and restaurant. I should have protographed the marble and tile on the walls, but I was actually working at the time, and I was in a hurry.
I'm sure the history of the building and more photos are available elsewhere on the internet. It's worth looking up.
