For 165 years, Croatian National Theatre in Zagreb has lived at the pace of the metamorphoses of drama – from actors and directors to dramaturges and intendants. Today, they have chosen to share this heritage with their audiences through a creative tool designed for interaction: the exhibition Drama165. The exhibition Drama 165 has been realised as part of the third Theatre Pop-up Museum. It offers a multi-layered view of the history of one of the key institutions of Croatian culture. Featuring a rich photographic archive and a carefully conceived concept, the exhibition centres on the idea of drama as a living, ever-changing organism that endures precisely through its transience. Generations of artists – from actors and directors to dramaturges and intendants – have shaped the identity of the Drama of the Croatian National Theatre in Zagreb, while audiences have for decades been its active participants. This dynamic relationship between continuity and disappearance, built over 165 years, can be explored in greater depth through the exhibition.
