Heading east on Main Street from the Upper Common to Monument Park, you will see a watering trough of the 1880's from the Fitchburg Historical Society that is now used for flower plantings by the Laurelwood Garden Club. Passing in front of the 1851 City Hall, renovated in 2020, you will pass in front of the Fitchburg Public Library, by architect Carl Koch. Opposite the public library is Monument Park, honoring the city's participation in the Civil War, and the Civil War Soldiers' monument by Boston sculptor Martin Milmore (1874).

Mill Street has been made a pedestrian street. After renovations in 2019, a public plaza at the end of Mill Street, next to Boulder Drive, is functioning as a flexible space for public happenings and art. The decorative panels were made by Fitchburg artists and designers. Two blocks further east on Main Street, you will find the area originally known as Depot Square, when it faced Fitchburg's monumental Victorian train depot, taken down as part of urban renewal in 1961. In that area, the city has mounted a monument to 9/11, a policeman's monument, and a display of flags representing Fitchburg's ethnic diversity and civic life.

The Fitchburg Abolitionist Park commemorates the men and women of Fitchburg who fought for the abolition of slavery. Beginning in the 1830s, Fitchburg residents participated in local, regional and national antislavery movements. Multiple homes were stations or depots on the Underground Railroad. The Trinitarian Church was established in 1843 as an antislavery church. Beginning in 1854, nearly 50 Fitchburg abolition supporters emigrated to the Kansas territory to ensure Kansas would enter the Union as a free state.In Summer 2022, a new mural is being painted to celebrate Fitchburg's Abolitionist history. Additional educational programs have been developed, including an ALFA program adult education class on the local abolitionist history, being offered at Fitchburg State University.
