The rich collection of the Natural History Museum in Budapest is worth a visit no matter what, but if you have only 10 minutes for education (or no money), this is also your place.
Situated in the charming neighbourhood of Ludovika Academy, the exhibition starts from the very first step into the building. After entering the hall you will face (sideways all to your right) the giant skeleton of a fin whale. Although it was bought by the state more than 120 years ago, the whale was never visible before as a whole until the new building of the museum was opened in 1996. The dome of the new hall was designed to host the remains of this amazing animal. The huge bones hang on 10 points and somehow the scene gives the impression of a temple. You can find out more about this creature on a board directly left from the entrance.
If you decide to stay, which personally is what I would absolutely recommend, after buying your ticket, do not miss to visit the mineral collection and the coral reef exhibition.
