The Čertovy hlavy ('The Devil Heads') are a pair of 9 metre high rock sculptures in the municipality of Želízy in the Central Bohemian Region of Czech Republic.
Čertovy hlavy were created by Václav Levý in 1841-1846. In terms of dimensions, it is a unique work in the Czech Republic. They are the second largest carved heads in the world, after the carvings of Mount Rushmore in the United States.
The sculptures have been damaged by time and weather. In 2011, the private owner had the surrounding pine forest cut down, allowing the heads to be seen from the I/9 road. Further sandstone reliefs can be found near the Čertovy hlavy, known as Harfenice ('Harpist') and Had ('Snake') reliefs.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
