Structural membranes have become a frequently preferred system type in long span structures such as amphitheatres, stadiums, performance centres, sport halls, with their ability to cover long distances by lighter solutions. The membrane material, which is the main component of the lightweight structures including membranes and has sufficient strength together with stretching, has very low weight of around 1 kg per sqm compared with the conventional load bearing materials. This is very important feature, both aesthetically and economically. Its light weight does not only provide an economical solution, but also allows to have better structural performance under seismic loads. Besides its lightness, another advantage of membrane-covered structures such as the amphitheatre is acoustic performance, which is an important one for the structure to meet serviceability requirements.

The "Medijana" project was designed to protect one of the most important archaeological excavation sites from the ancient Roman period in Serbia, and presented a significant challenge due to its location as a candidate for UNESCO heritage protection. In 2023, the project has been completed, with total covered surface of 12,000 m2, a main clear span of 80m and a length of 148m, one of the largest membrane structures in this region of Europe. The site-specific limitations and conditions required careful planning and logistics. As such, this project serves as a unique case study that illustrates the interplay between design, limitations, and consequently the need for innovative detailing and installation techniques. Through monitoring and observation over a period of 9 years, a wealth of information including wooden structure – membrane interaction, microclimatic conditions, and maintenance has been collected, which will be valuable for future developments, the field of membrane structures in cultural heritage applications and beyond.
