On this 90-minute boat cruise with DOORS OPEN Pittsburgh, go beyond the typical sightseeing tour as we sail to the tip of Herr's Island and reveal the secrets of the Allegheny River.

What ever happened to Allegheny City? Who are the Three Sisters? What does horseradish have to do with a floating house? For the answers to these questions (and more), join engineer and local bridge expert Todd Wilson and architectural historian Justin Greenawalt for a fresh and immersive look at the histories and mysteries of the Allegheny River.

We look forward to having you join us to explore Pittsburgh from the rivers, DOORS OPEN Pittsburgh style!
