MEMORY & RENEWAL By Robert Shaw Pfaffmann, AIA, AICP, Architect and Planner

In October 2009, with the famed shimmering dramatically at center ice of the (aka “the Igloo”), the Penguins began their fi nal season under the historic pivoting stainless dome. The genesis of the Arena didn’t include hockey back in the late 1940s when local judge Abe Wolk and department store magnate Edgar Kaufmann envisioned a retractable fabric roof for the Civic Light Opera.

The Burden of Preserving the Recent Past Fifty years later, the Civic Arena is a recognized architectural and engineering landmark: it is has been designated eligible for the National Register of Historic Places. With its still- working retractable roof, it is a one-of-a- kind building in the world, and worthy of preservation and adaptive reuse. The Pittsburgh Sports & Exhibition Authority (SEA), which owns the Igloo, has begun reviewing its future as required under state and federal law. (By the way, the “Igloo” nickname would influence

The role of the Arena in the context of the urban and social history of the Hill and the city is a confl icted one and the question of demolition needs our full attention and should not be considered without careful understanding of the social, economic, and historic impacts. Pittsburgh has an opportunity to demonstrate that an innovative, unique structure can have new life as a sustainable civic space and anchor for new development of the Lower Hill. We must ask ourselves, is history and the community served by demolition and erasure of our collective memory? Fifty years ago we could not have imagined that we would put museums and residences in old warehouses. The arena is the 20th century version of our old train stations and warehouses that were also considered by many as obsolete just 50 years ago. The words of perhaps the Hill’s best- known resident, playwright August Wilson, may point the way: “My plays insist that we should not forget or toss away our history.” While he was referring to his roots in the community and the culture he knew, his words challenge us to ask questions about the many histories and memories that exist—some good, some .
