Bunker is a non-profit cultural organisation that produces and presents contemporary theatre and dance performances, organises workshops and educational programmes, including the cultural education festival Drugajanje, conducts various research methods in the field of culture and organises a renown international festival, the Mladi Levi Festival. Since 2004, it has managed the Old Power Station, a contemporary theatre venue in Ljubljana.

The Mladi Levi International Festival is one of Bunker's most important annual events, bringing the most current stage performers from around the world to Ljubljana in late summer every year since 1998. It stands out for its demanding artistic profile, set in the field of contemporary progressive theatre, and takes pride in its reputation for discovering young talent. The festival has a distinctive atmosphere of creativity and vibrancy, a curious audience and social commitment.

The Mladi Levi Festival will be the framework for Performing Landscape. Rooted in the black box and the local environment, but keen to experiment with new forms and spaces, the festival will open up new dimensions of discovery of landscapes, new territories and nature through artistic practices for the artists and the audience.

Koseški boršt is an integral part of the urban forest in the Tivoli, Rožnik and Šiška Hill Landscape Park, as well as a part of the city’s cultural landscape that extends like a green wedge from the hinterland to the centre of Ljubljana. From the city centre at the Tromostovje Bridge, it is a good three kilometres air distance to Koseški boršt, and most of the way leads through the city park and forest area. In its own way, Koseški boršt is also a building block of the city's identity. Apart from the Ljubljanica River, it is the wooded slopes of the Castle Hill with its castle and the varied forest and parkland of the City Park, which acts as a protected nature and cultural heritage area, that create Ljubljana's identity to the greatest extent.

Ljubljana's Večna pot road cut through the forest landscape of Koseški boršt a long time ago and, despite the development of activities in the surrounding area, nature has been preserved in a good condition in much of this slightly wet forest area. Over time, new paths and trails have been added to the existing ones, helping to ensure that the area remains largely open to those who wish to connect with nature in the city and to explore the attractions of the urban surroundings, such as the views of the deer grazing in the forest glades and the water and shore area of the Koseški bajer pond.

Koseški boršt is a mixed forest, partly flat and wetland, growing on a predominantly siliceous base with acid brown soils. The tree layer is dominated by beech, oak, chestnut, sessile oak, spruce, fir and Scots pine, as well as rowan both as a tree and a shrub. The shrub layer is characterised by buckthorn and bilberry, and the herb layer is very rich. The area is home to many birds and other animals, including small carnivores, deer, foxes and badgers.
