Detwiller Plaza is a small park located near the historic center of Hellertown. The plaza is directly opposite the Hellertown Borough Hall complex and enjoys a high degree of visibility because of its location along Route 412 (Main Street), the most heavily-traveled road in the borough. Detwiller Plaza was constructed during the final years of the Great Depression as a Works Relief Project. It was officially dedicated in 1940, when it was named for Dr. Henry Detwiller, an early Hellertown settler whose grandson donated the triangular parcel of land on which the plaza now sits. Two of Hellertown's most iconic landmarks — the Plaza fountain and clock tower — are located in Detwiller Plaza. The clock tower's hourly chimes can be heard throughout the borough, and the fountain features multicolored lighting which is often adjusted on special occasions.
