In the very center of Petrinja, there is almost no building that has not been demolished or whose roof has not collapsed after the devastating earthquake of 6,2 according to Richter, which hit Sisak-Moslavina County on December 29, 2020.
Most of the buildings within the cultural and historical ensemble of Petrinja were damaged and some cultural assets were, unfortunately, completely destroyed. The center of Petrinja is one of the most valuable historical cores of continental Croatia and is a protected historical ensemble and the city center itself suffered the most during these earthquakes.The City Administration building was also badly damaged and is scheduled for demolition.
One of the most demolished buildings is the Petrinja High School and the Elementary School leaning against it. With its 160-year tradition, the high school in Petrinja is one of the oldest educational institutions in the Sisak-Moslavina County. The school survived two world wars and the Homeland War, but unfortunately succumbed to the destructive force of the Petrinja earthquake.
