Allegheny Courthouse

One of the most iconic symbols in downtown Pittsburgh is set to undergo a series of renovations that will preserve its history and bring it up to date.

Allegheny County has selected the firm of Perfido Weiskopf Wagstaff + Goettel to develop a Master Facilities Plan to restore the 126-year-old Allegheny County Courthouse.

The firm will assess the building’s heating, lighting, electric and security systems to determine what construction needs completed, according to Principal Sheldon Goettel.

Protesters responding to the acquittal of George Zimmerman filled the courtyard of the Allegheny County  Courthouse Wednesday at noon.

Their shirts read “White Supremacy Acquitted Zimmerman,” and they held signs that said “Pittsburgh for Trayvon.”

Neighborhood watchman George Zimmerman was acquitted Saturday of murder and manslaughter of 17-year-old Trayvon Martin in Sanford, Fla.
