Community Area #31, the Lower West Side is 3 miles southwest of the loop. The oldest section is known as Pilsen, named for the city in Bohemia, where many of the earliest settlers to the area immigrated from. The initial popularity of the area was as a place for Bohemians to rebuild after the Great Chicago Fire of 1871. The area west of Pilsen was known as the Heart of Chicago, and soon became as popular as Pilsen, and as immigrants from different countries came to America, many of them settled in Heart of Chicago. The housing is most often modest brick worker’s cottages and practical multi-unit housing, and the area is dominated by several monumental churches, whose influence and congregation’s popularity helped bring population and development to the area. Beyond the churches and residences, the Lower West Side also includes grand treasures by the biggest luminaries of Chicago architecture. Join us for a day on your bike digging the Lower West Side.
