The Val di Merse is one of most captivating but lesser known corners of Tuscany, lying at the far end of the Terre di Siena, the beautiful lands of Siena. A verdant and uncontaminated nature rich in brooms, oak and chestnut trees, is the great protagonist of this wonderful part of Tuscany, located between the Crete Senesi, the Val d’Orcia, and the Maremma.

During the medieval period, plenty of beautiful churches, forts and abbeys were built all across its territory; the Cistercian Abbey of San Galgano is the most popular and most scenic example of all these.
