Doksy (German: Hirschberg am See) is a town in the Czech Republic. It has about 5,000 inhabitants. It lies on the shores of Lake Mácha, and so it is a summer vacation resort. The surroundings are densely forested and Bezděz Castle atop the mountain of the same name dominates the local landscape. Many rock groups (sandstones) are also to be seen nearby.
A hypothesis claims that the Czech name of the town comes from a Celtic word dogs probably meaning swamps or water surface. The German name Hirschberg am See means deer hill by lake. A deer is even seen on the coat of arms of the town (see to the right).
