The trulli houses UNESCO site is magnificent. It is a modest size village of dry walled built houses with conical roofs. The whole village is preserved as a tourist site and is a mix of private houses and shops selling tourist gifts. Both shops and private houses are genuinely pleased to invite you in to explore the trulli. When we visited last week there was a festival being held in the village and a huge temporary market had been set up and it was very busy. We visited the church aand spent time in the main square listening to a silver band playing in the band stand. I would recommend a visit to the Museo Del Territorio which explains and demonstrates how the trulli are built. I think the museum admission charge was 7€ and was good value. The trulli are a must see attraction. We spent almost four hours exploring the whole complex. There are plenty of cafes and bars for refreshments and there are public loos at the coach park.
