The Franciscan monastery is the most valuable historical monument in Kadaň. The first mention of the original chapel dates back to 1470. Today it is used for museum purposes. The oldest cellar vaults with the Church of the Fourteen Holy Helpers, consecrated in 1480. The appreciation of its importance and rich history took on a concrete form and the Ministry of Culture of the Czech Republic included this project, which is mostly financed by the city and the Ministry of Culture of the Czech Republic, in the program of saving the architectural heritage of our country. Since 1999, the monastery cellars have housed a municipal museum with a permanent exhibition of mineralogical and archaeological attractions, demonstrations of mining and processing of mineral resources, as well as mining activities in the Kadaň region. Since May 2004, the city museum on the ground floor has focused on the urban conservation area, the cult of the 14th Holy Helper and partly the life of Franciscan monks. On the first floor of the monastery, visitors can admire the preserved original architecture of the building. The tour continues to include the church of the Franciscan monastery.
