Located across from City Hall , the park is named after former Portland mayor Terry Schrunk and neighbors the Plaza Blocks consisting of Chapman Square and Lownsdale Square . The park is not a city park , but instead owned by the federal government . Schrunk Plaza is across Third Avenue from the Edith Green – Wendell Wyatt Federal Building , and the plaza covers an underground parking structure for that building . That structure was the planned assassination site of Charles H. Turner in the failed plot by members of the Rajneeshees in 1985 to kill Turner , the U.S. Attorney for Oregon who worked in the building . There are several Taihu stones in the plaza which is a gift from Portland 's Chinese sister city , Suzhou in 1996
