Washington Park (also known as Washington Square) is a small public, urban park (1 acre) located in Downtown Dubuque, Iowa, USA. The park encompasses an entire city block, bordered on the north by West 7th Street, on the west by Bluff Street, on the south by West 6th Street, and on the east by Locust Street. The park is located between the city's post office and the Dubuque Museum of Art.
The block where Washington Park is located today was one of the original 35 blocks plotted out by surveyor G.W. Harrison in 1833 when the city was founded.During the summer of 2005, Washington Park underwent further improvements. The streets surrounding the park have been rebuilt, and the walkways in and around the park have been replaced. Lampposts designed to look like late 19th and early 20th century models have also been placed in and around the park.
