Štětí consists of ten municipal parts (in brackets population according to the 2021 census):[2] The town's name is derived from the Old Czech word ščetie, which was a term for the poles driven into the swampy terrain as a basis for the upper construction.

The highest point is the hill Újezdský Špičák at 348 m (1,142 ft) above sea level.

The eastern part of the municipal territory lies in the Kokořínsko – Máchův kraj Protected Landscape Area.

For centuries, it was part of the Mělník estate, owned first by Bohemian queens and later by various noble families.

In addition to agriculture and river fishing, Štětí was famous for the production of stockings.
