My new penpal Milan sends this postcard from his hometown. This is the 14th century church of St. Sigismund! The back of the postcard reads “Králova Lhota, Královéhradecký Kraj;
Kostel sv. Zikmunda (kulturní památka) postaven v roce 1344 v gotickém slohu.“ Google Translate helps me out with the following: Králova Lhota, Hradec Králové Region;
Church of St. Sigismund (cultural monument) built in 1344 in the Gothic style.
