According to the press service of the mayor's office, the 15 columns symbolize the cities of Ukraine that were among the first to experience a large-scale enemy attack. The pedestals are mounted with missile and shell fragments found during the recovery, and notched plates symbolize the number of times enemy missiles hit a particular city.
If you lean over and look into the mirror plate, you can see a reflection of your face with symbolic scars from missiles.
The exhibition was created by the Dobrobat Volunteer Construction Battalion, a non-governmental organization that restores buildings and infrastructure destroyed by the Russian occupiers.
