Dilworth Park, Urban gathering space at City Hall, Philadelphia, United States.

Dilworth Park is an urban park located on the west side of Philadelphia City Hall in Pennsylvania. It features planted lawn areas, fountains with programmable water displays, and glass entrances leading down to an underground transit station.

The site corresponds to William Penn's original Centre Square laid out in 1682 as the intended heart of his new city. In 2014, an outdated concrete plaza was removed and replaced with the park that stands today.

Glass panels along Market Street display stories of Philadelphia's development, featuring quotes from former Mayor Richardson Dilworth about city life. These surfaces invite visitors to learn more about the city while walking through.

The park sits at a major transit hub with direct underground access to several SEPTA lines, making it easy to reach from most parts of the city. It is fully accessible and offers something in every season, from the fountains in summer to an ice rink in winter.

An art installation called Pulse creates light patterns on the park's surface that respond in real time to train movements in the tunnels directly below. The light shifts as trains pass, so what visitors see above ground is quietly connected to what is moving underneath.
