The end of the 19th century saw the Kłodzko Valley turned into one of the most popular tourist regions. Many hotels, sanatoria, and spa were opened to the public in the nearby towns of Bad Reinerz (Duszniki Zdrój), Habelschwerdt (Bystrzyca Kłodzka), Bad Altheide (Polanica Zdrój), and Bad Landeck (Lądek-Zdrój). The area of the former county became a popular place among the rich bourgeoisie of Breslau (Wrocław), Berlin, Vienna, and Kraków. In 1910 the city had 17,121 inhabitants: 13,629 Roman Catholics, 3,324 Protestants (mostly members of the Evangelical State Church of Prussia's older Provinces), and 150 Jews. During the "November Pogrom" (9 November 1938), colloquially euphemised as "Kristallnacht", the synagogue was destroyed by an arson attack of Nazis. Most of the Jews emigrated and by 1939 there were only 25 of them left.
