Ivona Martinčić of Voona Design stitched a broken crocheted heart with yarn entitled "Love Cracks" in Zagreb, Croatia, to commemorate the earthquake of March 22nd. When the coronavirus spread to Europe, the heart became viral as an homage to the many heroes who helped heal the wounded city. People came to the "Healing Heart" to remind themselves that, despite challenges, there is always hope and that wounds can heal.

Many individuals came together to help clean, repair and rebuild the city damaged by the earthquake, despite the dangers of COVID-19. Builders working near the Heart are careful while repairing the nearby school so as to not damage the symbol of healing.
