Every year in September European Heritage Days opens up to the public the most interesting landmarks, buildings and premises, including those that are partially or completely inaccessible. Most events and open-house days take place, of course, on weekends, but during weekdays, you can have a look at places that are closed over the weekend, and become familiar with the process of conservation and restoration. A variety of special events are held as part of EHD, including lectures, concerts, town festivals, and competitions. Individual countries and cities announce their national themes, and the opening of European Heritage Days in the Czech Republic will be on September 6, 2014, in Opava.
