Propylaea is a sculpture/fountain on the Maumee River, in downtown Toledo, Ohio.

In the early 1980s, Owens-Illinois was building their new world headquarters at One SeaGate.

As a gift to the city, the company commissioned Dimitri Hadzi to design a sculpture to stand as the centerpiece of the SeaGate complex.

The sculpture is made from granite, and is nestled as a fountain on a reflecting pond between One and Two SeaGate.

Dimitri Hadzi described the use of water in the sculpture as a way of creating activity in the flat lands of Ohio.
