In the province of Siena, Tuscany, lies one of the most fascinating architectural wonders in Italy. Monteriggioni, built as a castle by the Sienese, is now one of the most important walled towns in the region. Completely intact, with a circular wall cited as a ‘round enclosure,’ in Dante’s The Divine Comedy, it’s a magnificent site. Structurally, the town is as it was originally, with several piazzas. The main one, Piazza Roma is dominated by a Romanesque church, off which small streets lead to public gardens, ancient houses, restaurants and gelaterias. As the perfect place for a medieval festival, on the first weekend of July one of the most famous medieval pageants of its kind takes place. Local people dress up in costumes playing merchants, cross-bowmen and friars, and jugglers, acrobats and jesters also attend, much to the delight of onlookers. With little traffic inside its walls, the town is a lovely place for children to run free.
