A Park Honoring
Our Fallen Heroes

St. Louis County Memorial Plaza
Clayton, Missouri, USA

HOK’s master plan for the St. Louis County government campus included design of the Police and Firefighter Memorial Plaza and monuments in a new public park to honor heroes fallen in the line of duty.

In addition to developing an appropriate setting for the urban memorial plaza, the design creates a safe, aesthetically pleasing street-level park with fountains, a grass amphitheater, benches and trees.

The plaza and ring meadow provide a gathering space for people using the adjacent government complex and for Clayton’s residents, employees and visitors.
