The Castle of Segonzano was built in the 13th century on a rock spur, around 100 meters above the valley. The place where it's placed was probably the site of a prehistoric hillfort. Built by Rodolfo Scancio, on the authority of the Prince-Bishop of Trento, Federico Vanga, the castle served as an important fortified site guarding the trade route passing through the Adige Valley and across the Cantilaga bridge on the river Avisio.
The fortress became hugely important between the 14th and 15th centuries. In the 14th century it was owned by the Scancio, Rottenburg and Greifenstein families and then passed, in 1424, to the Dukes of Tyrol.
When German painter Albrecht Dürer passed here on his first journey to Venice in 1494, he was so impressed by the gloomy walls of the fortress, that he dedicated two celebrated watercolours to it. In 1971, Durer's historic visit to the site was commemorated by two porphyry pillars, at Faver and Piazzo di Segonzano, marking the locations from which he was inspired to paint the two views.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.
