Spegelteatern, Independent theater in Mariatorget, Stockholm, Sweden

Spegelteatern was a free theater group based at Björngårdsgatan by Mariatorget on Södermalm in Stockholm. It occupied a theater venue on that street, with two stages used for its own productions and for amateur performances. Since the theater closed, the former auditorium has been used as a music studio.

Spegelteatern was founded in 1974 by Peter Böök, who led it artistically until spring 2009; Malin Westberg then directed it until it closed that autumn. From 1985 it performed Shakespeare outdoors every summer except 2000, starting with A Midsummer Night's Dream at Gripsholm Castle and later playing at castles around Stockholm. The company went bankrupt in December 2009, and the Björngårdsgatan premises became a music studio.

The troupe's motto, coined at its 1974 founding, was "We shall mirror the world without shattering the mirror." From 1985 it performed Shakespeare outdoors each summer (except 2000) at castles around Stockholm, starting with A Midsummer Night's Dream at Gripsholm Castle. Through the association Periskop, amateur actors young and old staged shows on the theatre's two stages at Mariatorget.

The theatre closed in 2009 and the premises on Björngårdsgatan by Mariatorget have since been used as a music studio, so there is no stage to visit. The address sits in the Mariatorget area of Södermalm, reachable by metro to Mariatorget station.

The theatre's motto, coined when Peter Böök founded the group in 1974, was "We shall mirror the world without shattering the mirror" — a play on the name Spegelteatern, "the Mirror Theatre". The premises on Björngårdsgatan have housed a music studio since the troupe went bankrupt in December 2009.
