West Town, northwest of the Loop on Chicago's West Side, is one of the city's officially designated community areas. Much of this area was historically part of Polish Downtown, along Western Avenue, which was then the city's western boundary. West Town was a collection of several distinct neighborhoods and the most populous community area until it was surpassed by Near West Side in the 1960s. The boundaries of the community area are the Chicago River to the east, the Union Pacific railroad tracks to the south, the former railroad tracks on Bloomingdale Avenue to the North, and an irregular western border to the west that includes the city park called Humboldt Park. Humboldt Park is also the name of the community area to West Town's west, Logan Square is to the north, Near North Side to the east, and Near West Side to the south. The collection of neighborhoods in West Town along with the neighborhoods of Bucktown and the eastern portion of Logan Square have been referred to by media as the Near Northwest Side. Neighborhoods Pulaski Park Pulaski Park is a neighborhood directly west of Goose Island and east of Wicker Park. The generally accepted boundaries of Pulaski Park are Ashland (1600 W) to the west, the Chicago River and Elston Avenue to the east, the Bloomingdale Line on the north, and Chicago (800 N) on the south (although some people extend the southern border only to Division Street). Pulaski Park derives its name from the historic park and fieldhouse that was designed by Jens Jensen between 1912 and 1914. 1,200 people were displaced, leading to the razing of a number of buildings while others were moved to nearby locations in the neighborhood. The park and fieldhouse were listed on the National Register of Historic Places on August 13, 1981. It became an official Chicago Landmark on July 29, 2003. The neighborhood borders on Polonia Triangle which was considered to be the center of Chicago's Polish Downtown, the city's oldest and most prominent Polish settlement, functioning as the capital of American Polonia. Because of this, the headquarters of many major Polish organizations in the United States were found in Pulaski Park such as the Polish National Alliance, the Polish Daily News and the Polish Women's Alliance. Pulaski Park is listed within "Polonia Triangle" as one of the 11 neighborhoods included in The Labor Trail which chronicles Chicago's history
