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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
