After 27 km you reach Buonconvento, traditionally a meeting place, a market place and even a battleground. Its rectangular plan has been bordered by the city walls since time immemorial, and within them you find some monumental buildings, stocked with memories of time past. Apart from the Town Hall, which is decorated with the coat-of-arms of no fewer than 25 of the podestà who governed the town until 1270, you should take time to visit the Val d'Arbia Sacred Art Museum, a magnificent example of the Liberty style, whose walls contain artworks from the churches across the Crete Senesi. You leave Buonconvento and, not far after Torrenieri, the Via Cassia rises over the unmistakable landscape of the Val d'Orcia, with San Quirico nearby. You will not have any difficulty noting the cypress trees that spike from the undulating hills, one of Tuscany's most famous features.
