In summer the park by the Zone's head office on Księży Młyn turns into the place of the #Grohmania picnics: bouncy castles, workshops, live music and a guided walk through the old factory. Free entry, no sign-up, just bring a blanket.

How the #Grohmania picnics work

For most of the year Fabryka Grohmana is offices and conference halls. In summer we open the gate and the park goes back to the neighbours.

Our head office stands in the old Grohman factory on Księży Młyn, among brick halls and a park with a pond where spinning mills and weaving sheds once worked. We have run picnics at the Grohman factory since 2013: by 2019 it was already the seventh edition, and today the series is called #Grohmania. What stays the same is the time (Sunday afternoon), the place (the park at 22G Tymienieckiego Street) and the rule: entry is free and needs no sign-up.

Every picnic has its own theme. In 2025 we partied in the style of “The Promised Land” with the Grohman Orchestra, in 1920s style with the band Tripper Stompers, to 1990s hits with a concert by Bohomaz, and at a “Picnic of the Future” with a DJ, roller skates and VR. In 2026 there were fairy-tale, sporting and historical picnics, and more than 300 people came to the last of them. Every picnic has a children's zone, workshops, a food zone, prize competitions and a Radio Łódź zone.

Bubbles, bouncy castles, a barber under a tent and an orchestra on stage. This is what the 2025 picnics looked like.
