The shore is lined by a long concrete wall (built 1905–1910), which is interrupted every ten feet by a squat pier, and by four lookouts that jut over the embankment.

The southern edge of the park abuts the properties that line the north side of St. Kolbe Street.

The center of the park has a small garden enclosed by a wrought iron fence, in which is a boulder on which is mounted a bronze plaque memorializing Casimir Pulaski.

[2] In 1884 the Holyoke Water Power Company, owner of the land, gave it to the city, and its formal existence as Prospect Park began.

Features built in this time that have not survived include a bandstand and an ornamental pump house used to bring water up from a spring in the river embankment.

[3] One of Holyoke's native sons, Polish-American historian Edward Pinkowski, would later re-discover Pulaski's forgotten burial site in Savannah, Georgia, in 1996.
