The built-up area is situated in the valley of the stream Jílovský potok, a left tributary of the Elbe River.

The town is located at the foot of the Děčínský Sněžník mountain, which is the highest peak of the municipal territory at 723 m (2,372 ft) above sea level.

The nearby Lotarův vrch mountain may already had been the site of the 1126 Battle of Chlumec between Duke Soběslav I of Bohemia and King Lothair III of Germany, whose exact location is unknown.

[5] After World War II, the German population was expelled and the Thun und Hohenstein properties were confiscated by the Czechoslovak Republic.
