The Prebischtor (Czech: Pravčická brána) is located in the Bohemian Switzerland in the Czech Republic. The narrow rock formation is the largest natural sandstone arch in Europe. With a span of 26.5 metres, an inside height of 16 metres, 8 metre maximum width and 3 metre arch it is one of the most striking natural monuments in the Elbe Sandstone Mountains.
In 1826 an inn was built by the Prebischtor. In 1881 Prince Edmund of Clary-Aldringen built the Hotel "Falkennest" (Czech: Sokolí hnízdo) with 50 beds.
As a result of heavy erosion by visitors, the arch has been placed out of bounds since 1982. The entire terrain has been in private ownership since the privatisation of the hotel and may be visited for an entry fee during opening times.
The Eisenach to Budapest mountain path runs by the Prebischtor.
Several landscape scenes in the film The Chronicles of Narnia: The Lion, the Witch and the Wardrobe were filmed here. Because the Prebischtor may no longer be climbed on, the scenes in which the actors appear to run over the arch were taken in the studio and pasted in.
