The present building of the museum was built between 1906 and 1907, after the design of the architect Victor Ştefănescu. The museum was established in 1892. In 1990 it reopened. The collections of the Geological Museum span three floors, comprising halls dedicated to mineralogy, petrography, the external and internal dynamics of the earth, paleobotany, palaeontology, stratigraphy, hydrogeology, Romania's tectonics, useful mineral substances, hydrocarbons, Romania's geology, florescent minerals and mining flowers. The museum is organized as a true geology manual open both to specialists and for those who know less about geology. It is destined to those who take a look into the inte...resting world of crystals, coloured or fluorescent minerals, rocks and fossils, wishing they could have a real understanding of the Earth, its composition, origin and history (the oldest rocks date back to 1,9000,000,000 years ago). The minerals and fossils described for the first time in Romania, the reconstruction of livestock that populated the Romanian territory in the geological past (reptiles, birds, hominids) next to real size dinosaurs are a few of the visitor attractions. The museum owns goods listed in the National Cultural Heritage Treasure.
