UPDATE: Looks like the Gulf Building goal siren can be seen from PNC Park during the Pirates games too!
The Gulf Building downtown has been turned into a giant Penguins goal siren!
Whenever there's a goal, the Pens have the ability to turn the colors on the top of the building to a 'rotating' red siren. Pretty sweet looking!
Check out the video of the 'Gulf Siren' after a goal in Game 2 vs. the Sens
