Where Is Dum Dum In Natural History Museum

Looking for Dum Dum at the Natural History Museum

I've gotten this question a handful of times from visitors and people planning trips, and it comes up in forums often enough that I figure it's worth addressing plainly. First, a clarification: there is no official exhibit called "Dum Dum" at the Natural History Museum in London or the one in New York. What people usually mean is the large diplodocus skeleton that hangs in the main hinting hall — the one nicknamed "Dippy." The confusion likely comes from mishearing or shorthand, or sometimes people are thinking of a different museum entirely. If you're looking for the suspended diplodocus skeleton that tourists flock to photograph, here's how it actually works in practice. At the London Natural History Museum, Dippy was displayed in the central Hinting Hall for over a century. In 2017, it was moved to the Earth Galleries on the basement level as part of a permanent replacement by a blue whale skeleton named "Hope." The original Dippy cast remains on display downstairs, but the position you see in old photos — hanging from the ceiling in the grand central hall — is now occupied by the whale. At the American Museum of Natural History in New York, there is no "Dippy" equivalent in the same configuration. The main dinosaur halls are on the second floor, and the famous Tyrannosaurus rex and diplodocus displays are in separate galleries. There's no suspended skeleton in the main rotunda area.

I remember a specific case where a visitor showed up expecting Dippy in the central hall, missed it entirely because they didn't realize the whale was there now, and ended up frustrated. The workaround is straightforward: check the museum's current exhibit map online before you go, and plan your route to the Earth Galleries at ground or basement level if you want the diplodocus cast. The whale skeleton is also worth seeing and is more visible from the main hall entrance. One thing most first-time visitors miss is that the Natural History Museum in London has multiple entrances and the floor plan isn't intuitive. The main entrance on Cromwell Road leads directly into Hinting Hall, so you see the whale immediately, but the exit traffic and crowds make it easy to just walk through without stopping. I'd recommend entering through the Exhibition Road side if you want to approach the whale and then head down to the Earth Galleries without fighting the crowd flow. The basement exhibits are signposted but the signage can get lost in the main hall rush. Another practical detail: the Earth Galleries where Dippy's cast now lives are free to access with your general admission ticket, but the museum occasionally rotates displays there for special exhibitions. It's happened twice in the last few years that the diplodocus was temporarily moved for a diorama installation. If this is your only reason for visiting, calling ahead or checking the museum's social media on the morning of your visit saves a wasted trip.

There's no download or digital tool that tracks these exhibits in real time beyond the museum's own website and app. Third-party museum guide apps often have outdated information about permanent displays, so I rely on the official resources. The museum's app does have a basic floor plan with exhibit markers, but it hasn't been updated to reflect the post-2017 layout in all its details.
