The neo-renaissance historical building of the Academy of Sciences was severely shattered on the morning of April 29, 2013 by a gas explosion, which occurred in the building two blocks from the side section of the Academy. A massive pressure wave smashed window panes and defaced parts of the interior not only the whole length of the building facing the explosion but also broke the glass of the windows toward the courtyard and some towards Národní třída (National Avenue). The greatest damage occurred in the Library and Head Office of the ASCR.
