The Lincoln Memorial underground museum is usually worth about 20 to 30 minutes on its own, and many visitors spend closer to 45 minutes to 1 hour if they read the exhibits and take in the views of the undercroft and columns. The new underground museum opened on June 25, 2026, and features 15,000 square feet of exhibit space beneath the memorial.

Typical visit length

  • Quick visit: 20–30 minutes.
  • Leisurely visit: 45–60 minutes.
  • With photos and reading: up to 75 minutes.

What affects the time

  • How crowded it is.
  • Whether you have timed-entry tickets.
  • How much time you spend on exhibits, artifacts, and the underground structure itself.

Practical tip

If you’re pairing it with the Lincoln Memorial steps and the rest of the National Mall, plan a half-hour to an hour for just the underground museum, then extra time for the memorial above ground.
