Wenceslas Square is one of the most important and busiest public spaces in Prague. The project involves the complete reconstruction of surfaces and technical and transport infrastructure of the square. The design includes a significant extension of alleys—from 2 alleys in the lower part to 3, and from 2 to 4 in the upper part—while employing principles of green infrastructure. To enhance biodiversity and ecological health, the project incorporates the most suitable lime tree taxa, selected with the assistance of dendrologists.
Wenceslas Square is one of the most important and busiest public spaces in Prague and in the country. It is the important scene of historical moments, a meeting place and a shopping boulevard, as well as the transport hub, situated in the very centre of the city. The architecture competition for the reconstruction of this complicated and closely watched place in 2005 marked the beginning of a long journey. Over the years, priorities shifted, yet the focus on traffic solutions remained paramount: a significant effort was devoted to constructing access ramps for the underground garages, that would destroy a large portion of the square.
By 2018, the focus on trees within the project had improved markedly, thanks to the initiative led by landscape architect Anna Salingerova from Jakub Cigler Architects. To further enhance the project, expert David Hora, specializing in urban tree planting and care, was enlisted to strengthen stormwater management strategies.
Originally, the plan included plane trees and complete tree replacement; however, community pressure from a civic association necessitated changes. The lime tree was ultimately chosen as the national tree, leading to a thorough search for the most suitable cultivar. Habitat and ecological parameters were assessed to align with cultivation objectives.
The project introduced innovative planting technology and nature-based solutions, utilizing structural substrates within structural cells and directing rainwater straight to the shared root space of the trees. Fortunately, these changes were permitted by local authorities. This development is considered a significant achievement in landscape architecture. In total, 52 new trees were planted in the lower section of the square, utilizing structural cell systems because of heavy traffic load. Furthermore, the trees are equipped with automatic irrigation for early years and later for eventual dry spells. Additionally, the upper section is set to feature 104 trees, all benefiting from irrigation supplied by a newly established rainwater retention basin, further promoting sustainable urban ecology.
