Many people know Ali, but a lesser-known fact is that he opened his own training camp in Pennsylvania, where he prepared for some of his most memorable fights.
Now, that training camp has become a museum honoring Ali's legacy.
Ali nicknamed the site "Fighter's Heaven."
It's located in the hills above Deer Lake about an hour and a half west of Philadelphia.
