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. Their style of construction is specific to the Itria Valley in the region of Puglia. Trulli were generally constructed as temporary field shelters and storehouses or as permanent dwellings by small-scale landowners or agricultural labourers.
The trulli of Alberobello represent a dry-stone building tradition, several thousand years old, found across the Mediterranean region. Scattered rural settlements were present in the area of present day Alberobello around one thousand years ago (1,000 AD). The settlements gradually grew to form the villages of present-day Aia Piccola and Monti. In the mid-14th century the Alberobello area was granted to the first Count of Conversano by Robert d’Anjou, Prince of Taranto, in recognition of service during the Crusades. By the mid-16th century the Monti district was occupied by some forty trulli, but it was in 1620 that the settlement began to expand, when the Count of the period, Gian Girolamo Guercio, ordered the construction of a bakery, mill, and inn. By the end of the 18th century the community numbered over 3500 people. In 1797, feudal rule came to an end, the name of Alberobello was adopted, and Ferdinand IV, Bourbon King of Naples, awarded to Alberobello the status of royal town. After this time the construction of new trulli declined.
The trulli of Alberobello have been designated as a UNESCO World Heritage site since 1996.References:
The historic city of Trogir is situated on a small island between the Croatian mainland and the island of Čiovo. Since 1997, it has been included in the UNESCO list of World Heritage Sites for its Venetian architecture.
Trogir has 2300 years of continuous urban tradition. Its culture was created under the influence of the ancient Greeks, and then the Romans, and Venetians. Trogir has a high concentration of palaces, churches, and towers, as well as a fortress on a small island. The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications. Its beautiful Romanesque churches are complemented by the outstanding Renaissance and Baroque buildings from the Venetian period.
Trogir is the best-preserved Romanesque-Gothic complex not only in the Adriatic, but in all of Central Europe. Trogir's medieval core, surrounded by walls, comprises a preserved castle and tower and a series of dwellings and palaces from the Romanesque, Gothic, Renaissance and Baroque periods. Trogir's grandest building is the church of St. Lawrence, whose main west portal is a masterpiece by Radovan, and the most significant work of the Romanesque-Gothic style in Croatia.
