STONE TEMPLE: LAPIDARIUM AT ŠPILBERK CASTLE

Špilberk Castle offers a new addition to underground Brno – Brno’s first ever publicly accessible water tanks. These two enormous tanks, built in 1870–71 and 1900, were created to hold water for the city and were used until the 1920s. After decades of neglect, they were repaired between 2017 and 2019 – the last part of Špilberk Castle to be renovated. Inside this exceptionally impressive space, reminiscent of a mystical temple, the Brno City Museum now presents its priceless collection of sculptures, gravestones, and stone ornamentation from former Brno buildings.
