The town centre with the castle and area of Křížový vrch are well preserved and are protected by law as an urban monument zone.

The highest point is located on the slopes of the Hrazený mountain at 567 m (1,860 ft) above sea level.

[3] During the reign of King George of Poděbrady, the property of Berka of Dubá was confiscated and Šluknov was acquired by Wartenberg family.

[4] During the Thirty Years' War, the town was repeatedly severely damaged by Swedish army.

Prior to World War II, Šluknov was a centre in Czechoslovakia for the pro-Nazist Sudeten German Party (SdP) led by Konrad Henlein.

This was one reason why, in March 1939, Adolf Hitler chose the town as the first stop of the Wehrmacht during the German annexation of Sudetenland.

After World War II, the town returned to Czechoslovakia and the German inhabitants were expelled under the terms of Beneš decrees.

There is persistently high unemployment rate, low supply of services and poor quality of healthcare.

Its main landmarks are the Baroque column of the Holy Trinity, built in 1751–1752, and an Empire style fountain dating from 1794.

[17] The hill Křížový vrch is a valuable complex of sacral buildings, including Stations of the Cross, several chapels and statues.
