Peavey Plaza, downtown Minneapolis’ celebrated modernist square completed in 1975, fell into disrepair—two of its three iconic fountains are no longer operational, and its sunken “garden rooms” have helped harbor illegal activity. Landscape architect M. Paul Friedberg’s plaza became the focus of a high-profile preservation battle two years ago, with The Cultural Landscape Foundation (TCLF) leading the charge to rehabilitate Peavey and city officials pushing for demolition.

Now TCLF has announced the plaza has been listed in the National Register of Historic Places. The “park plaza” style Friedberg forged is evident in Peavey’s blend of hard concrete squares and American-style green spaces. It joins 88,000 sites of architectural heritage on the list, only 2,500 of which have significance in landscape architecture.

Preservationists sued the city last year to contest city council’s claim that there were “no reasonable alternatives” to demolition, hoping to win protection under Minnesota’s Environmental Rights Act.
