Hostinné (German: Arnau) is a town in Trutnov District in the Hradec Králové Region of the Czech Republic.

The historic town centre is well preserved and is protected by law as an urban monument zone.

[3] From 1938 to 1945, the town was annexed by Nazi Germany and administered as part of the Reichsgau Sudetenland.

It was rebuilt in the Renaissance style in 1525, when the tower was added, but it preserved its late Gothic core.

It is among the most valuable town hall buildings in the country and since 2024, it has been protected as a national cultural monument.

Today, the monastery church houses a unique collection of plaster casts of ancient sculptures dating from 1912.
