Another coin joins to the "Discover Poland" series. Situated in the eastern part of the Łysogóry Mountains, the highest range of the Świętokrzyskie Mountains, the former Benedictine monastery on Święty Krzyż (literally Holy Cross) Mount, thanks to its historical and religious value, is a monument of particular significance for Polish culture and national heritage. Benedictine tradition, as recorded by Polish chronicler Jan Długosz, attributes the foundation of the abbey to Boleslaus the Brave in 1006. Contemporary historians postpone the date of the monastery’s foundation to the first half of the 12th century, during the reign of Prince Boleslaus the Wrymouth. At the beginning of the 14th century, the relics of the Holy Cross were donated to the abbey, making this place the most important and oldest sanctuary on Polish soil, as well as a pilgrimage destination for both Polish rulers and common people.
