While you may be familiar with the Penobscot (it's the one at Fort and Griswold with the huge red beacon at the top that lights up at night) here are a few factoids that show just how prominent the building once was.
• When it was built in 1928, it was the eighth tallest building in the world, and the tallest anywhere outside of New York and Chicago.
• It was the tallest building in Detroit until the RenCen was built in the '70s.
• Somewhat less impressive, its lobby was used during filming of "Eight Mile". You'll see it when Eminem walks through on his way in to a radio station.
• Its huge entrance arch alone is worth checking out, and looks much better when there isn't an SUV parked in the way of what otherwise would've been a nice picture.
