The museum Senckenberg in Frankfurt am Main is one of the largest museum of natural history in Germany. Its popular with visitors, mainly because of its dinosaur fossil collection. It has been in existence for such a long time that it has become an attraction of its own: not for being sciency, but for displaying weird exhibits. Apart from good old T-Rex, you can find a a very dusty, stuffed anaconda eating a pig. There´s the usual stuffed animals, but also the scull of a conjoined twin calf. There are also exhibition cabinets from the 19th century displaying specimens in jars, immersed in formalin- a rather gruesome attraction, but very interesting.
