The Franklin Institute

Overview

The Franklin Institute is one of the oldest and most prominent science museums in the United States, named after Benjamin Franklin. Its hands-on exhibits span physics, earth science, and technology, anchored by the iconic Giant Heart walk-through.

Highlights

• Giant Heart: A two-story walk-through model of the human heart — a Philadelphia icon since 1954.
• Fels Planetarium: The second-oldest planetarium in the Western Hemisphere.
• Train Factory: A 350-ton Baldwin locomotive that visitors can explore inside.

History

Founded in 1824 to honor Benjamin Franklin, the Institute originally focused on mechanical arts and applied science. The current Art Deco building on the Parkway opened in 1934. The museum has hosted over 30 million visitors.

Visitor Tips

• The Giant Heart is a must — kids and adults both find it fascinating.
• IMAX films require a separate ticket — the dome screen is worth the upgrade.
• Duration: 2–3 hours.
