The museum has long been a popular tourist destination with hundreds of thousands of people visiting it every year.Founded in 1991 at the site of a 1930s movie theater, the International UFO Museum and Research Center is situated in Roswell, New Mexico – home to one of the most famous alleged UFO incidents of all time.

Inside, visitors can find a variety of UFO-themed exhibits as well as a veritable library of material concerning the Roswell incident itself as well as the general history of the UFO phenomenon.

Some of its most famous exhibits include a miniature model of the Roswell crash site, an alien autopsy scene and even an interactive exhibit that puts you in control of an alien spaceship.

Now the museum is celebrating a major new milestone – 5 million visitors – with an unsuspecting father and daughter from Roswell itself winning free lifetime membership.

In total, around 220,000 people descend on the museum every year from all over the world.

It also serves as the focal point of the popular UFOfest event that is held in the town every year.
