A new geological open air geological exhibition was opened in the revitalized quarry Práchovna located at the southern edge of Kutná Hora (Předměstí) in August 2014. It collects 42 blocks of the characteristic rock types from the Kutná Hora crystalline unit and its geological neighbourhood and provides accompanying information panels with maps and rock descriptions. Each block carries a short rock title also in Braille. The geological content was mastered by the Czech Geological Survey, the technical part was kindly supported by Silnice Čáslav, Ltd., NGO Denemark, and the Kutná Hora Municipality.
