Łazarz's most popular park originated in 1834 as a tree nursery supplying plants for local streets and squares during the district's rapid expansion. In 1902 the land was handed over to city authorities, who soon used it to create Poznań's first botanical garden (no longer in existence), followed by the Palm House. After the Great War the park was renamed in honour of US president Thomas Woodrow Wilson, whose imposing bust now sits opposite the main entrance. For a while in the 1920s there was talk of building a planetarium, a project which unfortunately never came to fruition; instead, a fountain made an appearance in 1929, just in time for the Polish General Exhibition which took place in Poznań that year.
