The Theatre Night is a part of the European project called European Theatre Night, during which theatre art is presented in a creative and unusual form. It is held the third Saturday in November since 2008. 
The Theatre Night offers unusual experiences such as workshops for children and adults, theatre tours, discussions with actors, stage designers and directors, and other formats of theatre meetings that cannot be found anywhere else.  The Theatre Night in the Czech Republic, coordinated by the Arts and Theatre Institute since 2013, has become one of the biggest theatre festivals in Europe due to hundreds of events in about 40 cities and places in the Czech Republic.
