Charles IV's Gothic treasure castle above the Berounka valley
Karlštejn rises out of the forest above the Berounka river like a castle from a storybook, its walls climbing in steps from the gatehouse to the massive Great Tower at the top. It was built not as a fortress for battle but as a treasury: Charles IV, King of Bohemia and Holy Roman Emperor, wanted a secure and sacred place for the crown jewels and his collection of relics.
It is one of the easiest castle trips from Prague. Trains from the main station reach the village below in around 40 minutes, and from there a walk uphill through the village brings you to the gate. Inside, guided tours lead through the imperial residence, and a separate, smaller tour takes visitors into the castle chapels, including the jewel-like Chapel of the Holy Cross.
Charles IV founded Karlštejn in 1348 and personally oversaw its building and decoration; the work was directed by Vitus of Bítov. The Chapel of the Holy Cross in the Great Tower was consecrated in 1365. It was the heart of the castle, where the imperial regalia, the Bohemian crown jewels and holy relics were kept, and tradition says Charles entered it barefoot.
During the Hussite Wars the imperial regalia were taken away, and in 1422 Hussite forces besieged the castle without taking it. The Bohemian crown jewels were kept here for almost two more centuries until they were moved to Prague in 1619. After the Thirty Years' War the castle fell into disrepair, and its present appearance largely comes from Josef Mocker's Gothic Revival restoration of 1887-1899.
Karlštejn village lives largely from castle visitors, with its main street lined with stalls and cafés leading up to the gate. The castle is a powerful national symbol tied to Charles IV, whose reign is remembered as a golden age for Bohemia, and it is one of the most visited castles in the country.
Choose a guided tour before you go: the basic tour covers the imperial residence, while the exclusive chapels tour includes the Chapel of the Holy Cross and has small groups and limited dates, so it should be booked well in advance. The walk up from the station through the village takes some time and is uphill, so allow for it when picking a tour slot.
The surrounding Bohemian Karst protected landscape has marked walking trails through limestone hills and woods, and you can combine the castle with a hike along the Berounka or to nearby viewpoints before taking the train back to Prague.
May to October is the main season, when all tours run and the woods are green. Autumn colours in the Berounka valley make October especially attractive. In winter the castle opens only on selected days with a reduced programme and the chapels tour is closed, so check the official calendar.

Beroun, a short train ride further on, is the nearest larger town, and the Bohemian Karst protected landscape surrounds the castle with walking trails.
