Unesco World Heritage Site Alberobello resembles an urban sprawl. The "Zona dei Trulli" on the western hill of town is a dense mass of 1500 beehive-shaped houses, white-tipped as if dusted by snow. These dry-stone buildings are made from local limestone. Within the old town quarter of "Rione Monti" more than 1000 trulli cascade down the hillside, most of which are now souvenir shops. The area is surprisingly quiet and atmospheric in the late evening, once the gaudy stalls have been stashed away. Opposite of "Rione Monti" there is "Rione Aia Piccola". This neighbourhood is much less commercialised, with 400 trulli, many still used as family dwellings. "Trulli on foot" is not a touristic guide, but a way to walk with the tourist around Alberobello historic centre to enjoy its beauty. The map indicates the most important Points Of Interest in Alberobello and six different walk paths; therefore arm yourself with "Trulli on foot" so that you can easily navigate Alberobello in different paths, no pain to lose yourself. So turn your GPS on and stroll around the old centre of Alberobello!
