Castello di Casole, A Belmond Hotel: 4,200-acre 10th-century castle estate in Tuscany with Tosca dining, heated infinity pool, and Essere Spa

Spanning 4,200 private acres of rolling Tuscan hills, organic vineyards, ancient olive groves, and oak forests in Casole d'Elsa near Siena, Italy, Castello di Casole, A Belmond Hotel opened as one of Italy’s largest and most magnificent private castle estates. Dating back to the 10th century (with origins traced to the Etruscan civilization), the 39-room castle and luxury farmhouse collection preserves ancient stone ramparts, terracotta vaults, and hand-hewn wooden beams. Featuring the acclaimed restaurant Tosca, the rustic Emporio del Castello, a heated outdoor infinity swimming pool framing the Tuscan valleys, and the subterranean Essere Spa in the former wine cellar, this property is Tuscany’s ultimate castle haven.

Arrival introduces travelers to unvarnished 10th-century Tuscan aristocratic majesty: personal hosts greet guests at the castle courtyard beside stone archways with chilled estate-produced wine, warm focaccia, cold scented towels, and panoramic vistas of the rolling hills. Day-one logistics focus on coordinating bespoke Tuscan countryside, wine, and cultural pursuits: walking or biking through the 4,200-acre estate on private trails, taking private truffle hunting excursions with estate lagotto dogs in the private oak woods, swimming in the heated outdoor infinity pool framing the Montagnola Senese hills, exploring Siena and San Gimignano (25 minutes away), indulging in olive oil and wine therapies at Essere Spa, taking watercolor painting or stargazing sessions, and reserving dinner at Tosca.

Castle living balances historic agricultural discovery with serene Italian wellness: the Essere Spa is set within the former stone wine cellars, featuring barrel-vaulted treatment suites, vitality pool, steam rooms, and therapies utilizing estate-grown rosemary, olive oils, and red wine extracts. Dining is a celebrated Tuscan culinary summit: refined regional gastronomy at Tosca (featuring handmade pici pasta, Florentine bistecca, estate olive oil, and Super Tuscan Grand Crus), wood-fired pizzas at Bar San Rocco, and private wine tastings in the enoteca.

Accommodations comprise 39 rooms, suites, and private restored stone villas ranging from 45 to 140 square metres. Each residence features custom Italian antiques, exposed brick and stone walls, panoramic views of the Tuscan landscape, plush king beds with custom linens, and travertine marble bathrooms with deep soaking bathtubs and custom Belmond amenities.

Castle purists, wine connoisseurs, and luxury travelers seeking 4,200-acre Tuscan seclusion, heated infinity pool drama, and Tosca dining in Italy should book Castello di Casole without hesitation. Travelers seeking generic city center hotels should look elsewhere.
