One of the first uses of dioramas in a museum was in Stockholm, Sweden, where the Biological Museum opened in 1893. It had several dioramas, over three floors. They were also implemented by the Grigore Antipa National Museum of Natural History from Bucharest Romania and constituted a source of inspiration for many important museums in the world (such as the American Museum of Natural History in New York and the Great Oceanographic Museum in Berlin) [reference below].
