The article explores the features of the architectural development of theater forumexhibitions as an important factor in the growth of theater within contemporary society. Theater is a powerful cultural expression, and even during the war in Ukraine, there is a resurgence of national culture. International experience shows that theatrical forums, such as those in Prague, Avignon, and Venice, serve as key platforms for presenting theater and architecture. Lviv, with its rich theatrical history and architectural heritage spanning from the 11th to the 21st century, still lacks its own international forum. Therefore, an architectural and spatial concept for the Lviv Theater Triennale has been proposed — a model that integrates global experience with local traditions. In the works of Professor V. Proskuryakov and the faculty of Lviv Polytechnic, ideas of architecture and scenography at international theater forums, as well as concepts for Ukrainian pavilions at PQ 2015/2019, are discussed. The aim of the article is to highlight the phenomenon of theater forums with the goal of developing a concept for a theater forum in one of the world’s theatrical “capitals” – the city of Lviv. The article analyzes the experience of theater forums in various cities around the world, focusing on the architectural features of permanent and temporary structures. It examines the integration of performances with the architectural environment, where historical and contemporary spaces create flexible cultural platforms. The article presents an architectural-spatial model of the Lviv Theater Triennale, which combines global experience with Lviv’s unique traditions. The study demonstrates that Lviv deserves its own international forum, which would foster the integration of Ukrainian theater into global culture, encourage creativity, and draw international attention to Ukrainian culture during the ongoing struggle for independence.
