Egerberk is a ruined castle near Klášterec nad Ohří. First mentioned in 1317, the castle belonged to Wilhelm who first started to bear the attribute name 'of Egerberg'. Wilhelm was a friend of John of Luxembourg and accompanied him on his journeys. His brother Fritz was given several villages and started to bear the name of one of them - Pětipsy. The castle was then sold to the House of Šumburk from a nearby castle. In 1384 Egerberk was added to the property of the House of Škopek and Jindřich Škopek z Dubé started a large-scale reconstruction. At the end of the 16th century the castle was already abandoned.
References:The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
