Home Sweet Dome

For a half-century, Pittsburgh’s iconic Mellon Arena, an engineering marvel and shining symbol of the city’s post-war renaissance, has hosted championship teams, all-stars, icons and legends. Now, the landmark is ready for a swan song of its own. Join us for a last look back at life under the dome we called home.

Inside the heart of every Pittsburgher is a shiny dome. You know it as the Civic Arena, Mellon Arena or “The Igloo.” Of all the buildings that make up the city’s signature skyline, few have had more of an impact on our lives. If you’ve grown up in the Pittsburgh region, most likely you can name the concerts, games and events you’ve attended beneath its silver dome.

A lot has changed since the Civic Arena first opened its doors in 1961. Throughout that timeframe—nearly a half century—Pittsburgh has become famous for many things. Light opera is not exactly one of them. But that very art form helped to build the structure that fans would later come to know as Mellon Arena and “The Igloo” with its rich, storied and sometimes magical history.The Civic Arena  anticipates a 1974 tennis playoff between the Pittsburgh Triangles and  the Detroit Loves. An open arena was a common sight during these  matches, which were held during the summer months.

In the mid-1940s, Edgar Kaufmann, the Kaufmann’s department store magnate, grew tired of sitting in the rain during Civic Light Opera performances at the University of Pittsburgh’s stadium. He pledged $1 million of his own money to help build the CLO a new home—but with one condition: The new facility had to include a retractable roof so he and other patrons could enjoy performances under the stars.

At about the same time, Pittsburgh Mayor David L. Lawrence was pushing his Renaissance initiative and was desperately looking for a way to show the country that Pittsburgh had shed its “Smoky City” image. What better way than to build a massive, open-air structure unlike any other in the world?

“When it was first designed, it was a fabric-roofed, single-use structure intended only for the CLO,” says Pittsburgh-based architect Rob Pfaffmann, who is leading the preservation effort to save the building. But when they actually thought about what Pittsburgh needed, that’s when they went to the ‘hard top’ design … for a lot of different uses.”

As Pfaffmann goes on to say, “That was the first time people used architecture to show that we had changed as a city. It really put Pittsburgh on the map.” (Check out Pfaffmann’s alternative plan).

The highlight of the design by Pittsburgh architects Mitchell and Ritchey was the retractable roof, which was—and still is—truly an architectural achievement. It’s constructed of eight metal sections, which are supported by a cantilever arm—the half-arch that looms over the dome. Six of the eight sections rest on enormous steel wheels, which roll on top of a monorail-like track. To open the roof, motors pull the six retractable sections underneath the two stationary sections, revealing the Pittsburgh skyline to the audience in just more than two minutes.
