You might say that the heart is the "engine of life." In fact, that's what our world-famous Giant Heart exhibit was originally called back when it opened in 1954.
We like to think that our Giant Heart drives the pulse of the City of Brotherly Love, with nearly a million visitors per year getting an inside look at the path blood takes as it passes through the heart.
But whether you're able to visit us or not, The Franklin Institute is dedicated to educating people about how the heart works – and how to keep it healthy.
