The trulli of Alberobello really are world famous making the town an attraction for tourists who flock there in their thousands to view this unique spectacle.
Built by the poor over the centuries, the trulli were originally built as homes or sometimes for storage, out of the local limestone which is plentiful in the area. The walls are very thick and constructed in a similar way to the dry stone walls that can be seen everywhere separating the fields and boundaries. If you get the opportunity to stop and look at a ruined trulli, you will be able to see the method of building, with an inner and outer skin of larger stones and a rubble fill between them. This form of construction gives a good waterproof building and well insulated from the outside temperatures.
The simplest single cone trulli have just one open area with perhaps a single or two small alcoves off the central area for sleeping. Many have been extended over time to form a complex of rooms and living space, easily spotted by the multitude of cone roofs. Many of the Alberobello trulli are topped with a carved pinnacle and have a symbol painted on the roof, some of these are obviously Christian but others have probably pagan or mystical meanings lost in time.
In the last decade the trulli have become increasingly popular as a second or country home for both Italians, Germans and increasingly the British. Renovated and bought up to modern standards trulli to rent command a premium price due to the novelty value. In the countryside they invariably have a large garden area often full of fruit, almond and olive trees making a pleasant backdrop.
