On Aug. 17, hours before British guitar hero Mark Knopfler played to a sold-out crowd, Live Nation unveiled a majestic sign on the roof of the Met Philadelphia. The new rooftop display, set like a crown atop the 3,400-seat venue, is the finishing touch on the recently restored landmark at 858 N. Broad St. The Metropolitan Opera House, erected by Oscar Hammerstein in 1908, fell into disrepair and neglect following the decline of North Philadelphia in the 1970s and ’80s. In 2017, concert promoter Live Nation partnered with developer Eric Blumenfeld, who co-owns the building with the Holy Ghost Headquarters Church, on a $56 million renovation. The 110,000-square-foot building reopened in December.
