Epcor Centre for Performing Arts

The "Plus 159 System", linked to the Municipal Building, provides access to the modern 1985-built Epcor Centre for Performing Arts on the south side of the square at 205-8th Ave. S. E. Comprising three stages and the John Singer Concert Hall, the Epcor Centre for the Performing Arts is connected to two older buildings, Calgary Public Building (1930) and Burns Building (1913).

This is where many of Calgary's stage performances are held. The Epcor Centre for Performing Arts is home to Alberta Theatre Projects , the Calgary Philharmonic Orchestra, the Calgary International Children's Festival, Theatre Calgary, as well as other companies.
