In June 1991, independence of Slovenia was proclaimed in front of the state parliament in the centre of Ljubljana. The event called for an inspiring visual backdrop, achieved with series of temporary interventions in surrounding area, as well as defining and positioning explicit state symbols in the square. A mast with a flag originally 14 meters long was erected in the axis of the parliament, and next to it a lime-tree, the national symbol, was planted. With the lack of natural soil in the existing square structure, a suspended cube with in-built watering and heating system was incorporated into the adjoining open atrium.
