The Troja Basin and Imperial Island

The competition workshop, which took place during May and June 2015, represented the preparatory phase of the future Concept of the Imperial Island. It combined a competition and an expert colloquium with broad participation. Its aim was to find a shared approach to the development of the area and to select the winning project from the five proposals that emerged continuously between the first and third meetings.

The design respects the environment and responds sensitively to the uniqueness of the area Troja basin. The project supports the variability of the landscape, brings agency to it and naturally addresses the free flow of water during floods.

Concept and action plan

The Troja basin lacked a universally shared concept of spatial development. On 29 August 2017, the Prague City Council approved the Action Plan and Concept for the overall landscape design of Imperial Island and its wider surroundings. The Action Plan divides the entire area of the Troja Basin into smaller units, which are gradually being developed.

Restoring Coexistence with the River (2016)

The aim of the exhibition and accompanying activities was to raise public awareness of the values of the riverscape and how to develop and protect it. The exhibition talked about the past, present and future of the Troja Basin and the coexistence of man and the river. The educational game in the area of the old sewage treatment plant loosely linked to the exhibition Restoring Coexistence with the River continues today.

Riverscape (2019)

The river doesn't end at the bank. Its story is written into all layers of the city and landscape. IPR Prague has prepared an exhibition about the riverscape and its significance. The installation by the banks of the Štvanice River is as changeable as the river itself.
