Teatar Tirena je kazalište za djecu i mlade čije su se djelatnosti tijekom 23 godine postojanja razvijale u četiri smjera: kazalište, dramski studio, edukativne aktivnosti i izdavaštvo. U Tireninom kazalištu do sada je uprizoreno četrdesetak predstava (od toga 13 interaktivnih), koje su se bavile temama kao što su mentalno zdravlje, tolerancija, ovisnosti, nasilje, gubitak… U Tireninom dramskom studiju radi 11 dramskih pedagoga koji na 7 različitih lokacija vode 25 dramskih grupa raznovrsnih uzrasta koje pohađa oko 250 polaznika, od predškolaca do studenata. U Tireni se u sklopu Kazališnog kampa od 2004. godine održavaju i radionice namijenjene razvijanju kazališne kulture, kreativnom i estetskom razvoju djece i mladih te edukaciji voditelja aktivnosti za djecu i mlade. U Biblioteci Tirena izdana su tri zbornika igrokaza i jedan priručnik, u planu su dvije nove publikacije. Tirenin najnoviji projekt je Kazališni šalabahter, besplatna online publikacija koja služi kao uvod u kazališnu umjetnost, podsjetnik na njene poznate i manje poznate pojmove i pomoć pri gledanju predstave te analizi odgledanog uz pomoć upitnika.
Tirena Theatre is a performing arts company for children and youth that was founded 23 years ago and works across several fields of interest: theatre, drama studio, theatre workshops and book publishing. Tirena has staged around 40 shows for children and youth (13 of those shows were TIE projects) that dealt with topics such as mental health, tolerance, addiction, violence, loss… Tirena’s drama studio has 25 drama groups on 7 different locations in Zagreb, which are led by 11 drama pedagogues. There are approximately 250 students of different ages, from preschoolers to college students. Tirena has been organising Theatre Camp since 2004., theatre workshops that aim to champion theatre culture, creative and aesthetic development of children and youth and to educate grown ups who work with children. Tirena also published three collections of plays for drama groups, and one handbook, two new publications are in development. Tirena’s newest project is the Theatre cheat sheet, a free online publication which serves as an introduction to theatre, a reminder of the meaning of different theatre terms and it aims to help with analysing theatre shows.
