Alberobello is a city in Puglia, in Italy. It is known for the Trulli, white conical buildings in stone, present in hundreds in the Rione Monti hilltop district. The Trullo Sovrano of the eighteenth century is a trullo on two levels. The “Casa Pezzolla” Territory Museum displays furniture and tools that recreate life in the Trulli as it was in the past. To the south-west of the city is the Red House, an internment camp of the Second World War.
