The ancient dry stone masonry technique was used to build trulli houses, which involves the use of stones without the application of mortar. The stones are cut into an octagonal shape to ensure stacking stability without falling. The conical shape of the trullo roof is constructed using limestone slabs, enabling the collection of rainwater for the house's use. The unique construction technique used is material-driven resulting in cold houses in the winter season due to the lack of insulating materials. Show more
