Henryk Jordan's biggest achievement was to set up a public playground in 1889, with exercise fixtures modeled after playgrounds in the USA, the first in Kraków and perhaps the first in Europe. The Jordan’s Garden built on the grounds of Kraków’s Błonia included a swimming pool, 12 playing and soccer fields, as well as numerous running and exercise tracks. Facilities were added for indoor activities in 1906, in case of bad weather. The park was equipped with locker rooms and showers. On top of that, a free meal service was established for the children.
