European Heritage Days have been organized since 1999 as a joint action of the European Union and the Council of Europe. The participant countries to the European Cultural Convention take part in European Heritage Days by putting new cultural assets on view and opening historical buildings normally closed to the public. In Budapest, buildings and listed monuments open their gates to the public. Cultural events highlight local skills and traditions, architecture and works of art. Organized tours are held, to promote mutual understanding among EU citizens. This year’s event on September 21-22 focuses on historic places of entertainment: theaters, cinemas, concert venues, ball rooms and even brothels.
