Union Station Square is a 1600 square foot triangle of green at the intersection of Jackson, 3rd Ave S and 2nd Ave.

Acreage: 0.04


Union Station was built in 1911 by the Oregon-Washington Railroad Company and the Chicago, Milwaukee and St. Paul Railway. The diagonal 2nd Ave was cut through in 1928, taking out a 7 story building at 3rd and Jackson, leaving a triangle street area. This 1600 sq.ft. piece of lawn became Union Station Square in 1929.
