Kraków's Main Market Square Gets a Greening Plan With Real Numbers
After years of consultations, heritage reviews, and a pilot scheme that planted pines instead of shade trees, Kraków's Main Market Square is finally moving toward a concrete greening program. On 2 September 2026, the city's Municipal Greenery Authority launched a public tender for the planting work, valuing the contract at more than 2.8 million zlotys. Bids were scheduled to open on 17 September 2026, and the contractor will have 580 days from signing to complete the work, meaning new trees should be visible on the square by spring 2028 at the latest. These details were first reported by Architektury i Biznesu (A&B).
What Will Actually Be Planted, and Where
The project unfolds in three phases, each targeting a different part of the square.
The first phase covers the eastern and southern sections. Ten trees will surround St. Adalbert's Church: three "Monument" oaks and seven "Brabant" silver lindens. Two "Greenspire" small-leaved lindens will also go in near the existing solitary tree between the Adam Mickiewicz monument and the fountain.
The second phase focuses on the area around the Town Hall Tower, near the northwest corner of the Cloth Hall, where twelve field maples are planned. Under good conditions, field maples can reach more than 15 metres, so this cluster has the most potential to create genuine shade over time.
The third phase fills gaps in the rows along the northern and western edges of the square with six black locust trees.
The net addition is 17 trees: 30 planted, 13 removed. Thirteen trees are being taken out because of poor condition, including four near St. Adalbert's Church and nine black locusts near the Town Hall Tower. The largest existing trees on the square will stay.
Engineering Under a UNESCO Site
Planting trees in a medieval square sitting above an underground museum and a web of utility lines is not straightforward. Each new tree will go into a specially designed planter fitted with anti-compression boxes, allowing root systems to expand without damaging the archaeological remains beneath the paving. Additional protective work around utility lines is also required, and new openings will be cut into the wall surrounding St. Adalbert's Church.
The landscape architecture design was prepared by a team from the Kraków University of Technology, including specialists in conservation, landscape architecture, and urban heritage.
The Bigger Picture: Expectations vs. Reality
The project traces back to a 2022 participatory budgeting vote in which more than 20,000 Kraków residents backed a proposal to plant trees on the square. The stated goals were straightforward: reduce the heat-island effect on a nearly four-hectare expanse of paving and give people somewhere to sit in the shade on hot days.
A&B notes that the outcome, while positive, will not transform the square. A net gain of 17 trees will create small pockets of coolness once the plantings mature in several years, not a shaded park. The square's UNESCO World Heritage status limits how far any intervention can go, and the underground museum beneath the paving adds further constraints.
For those hoping for more ambitious greening in the Old Town, the redesign of St. Mary Magdalene Square on Grodzka Street offers a parallel opportunity. Consultations on that project closed in April 2026, and their results will feed into a design competition for the square's new layout.
Why It Matters for Hosts
Accommodation operators and café owners near the Main Market Square can expect construction activity in phases through to early 2028, with the eastern and southern sections affected first. Communicating the timeline honestly to guests, particularly those booking summer stays, helps manage expectations. On the positive side, the mature trees around the Town Hall Tower and the Cloth Hall will eventually make that corner of the square a more comfortable place to linger, which tends to extend the time visitors spend in the area and benefits nearby businesses.
