The National History Museum of Sofia is the largest museum in the country, and one of the largest in all the Balkans, it houses more than 700,000 artifacts from different eras (only 10% of these are exhibited) and the oldest of them are dating back to 8000 years ago! The Museum was established on May 5, 1973, and the first exhibition was made in 1984 in the building of the Court of Justice for 1300th anniversary of the Bulgarian state. Since the year 2000, the Museum has changed its location to an imposing government building in the Boyana district, just outside the city of Sofia, where it is still today. The new building is a remarkable example of Soviet-style architecture, its rough and massive appearance and the large exhibition halls anticipate the importance of the treasures kept inside. The collections cover a lot of time periods, different for each hall of the museum, and the archaeological finds come from all over the country.
