There are three branches to the Budapest History Museum each in a different location – the Roman Antiquities Museum (Aquincum Museum); the Fine Art Museum (Kiscelli Museum) and the Castle Museum. The museum was established in 1887 and the main branch (Castle Museum) moved to its present location in building E of Buda Castle in 1967. The museum exhibits both temporary exhibitions and its permanent collection. The collection covers the history of the city from prehistory to the end of Soviet occupation.

Exhibition space is spread over three floors and there are six main sections in the museum. The Budapest in the Modern Age section is at present under construction but when it reopens you will be able to see artifacts from the 20^th century including political posters. The Gothic Sculptures from the Royal Palace of Buda section displays the works found in the castle. The section on Budapest in the Middle Ages holds artifacts related to the city during that period. The Medieval Royal Palace of the Buda Castle takes visitors to the lower levels of the castle where restored sections of the 15^th century medieval Royal Palace were once home to Hungarian kings. Within the castle you can see three halls with vaulted ceilings. One of the halls has a Renaissance red marble door frame which holds the seal of Queen Beatrice. Other rooms of interest in the castle are the 14^th century Tower Chapel and the Royal Cellar. A section entitled The Tapestry with the Hungarian-Angevin Coat-of-Arms displays a tapestry which was one of several silks found buried in mud 33 feet down inside a well. The section on Ancient Peoples and Antique Cultures holds artifacts discovered in archaeological excavations.
