What will theatre look like in the 21^st century? What role should it have in contemporary society? How should it be incorporated into the existing organism of the city or town? These are some of the questions whose answers were sought out for by architecture students from five Central European countries during the workshop “Theatre Architecture, Visions and Possibilities” which took place from the 18^th to the 20^th of March 2009 in Ljubljana, Slovenia. Thanks to a project of the National Theatre in Prague, TACE – Theatre Architecture in Central Europe, 70 students from Czech, Hungarian, Polish, Slovak and Slovenian architecture schools were able to participate as well. They had a difficult task to solve, that being the design for a new theatre in Ljubljana which would fit suitably into the historical centre of the city and at the same time meet all the requirements for modern theatre operations.
