Since the Middle Ages in Venice, several of the islands in the Venetian lagoon between the Grand Canal and the Lido leading to the Adriatic Sea were used as refuges for monks seeking solitude or for victims of the plague and other contagious diseases. Now that isolationist approach is being tested—on a luxurious scale—on one such abandoned island of the lagoon, home to the new JW Marriott Venice Resort & Spa, the luxury brand of Marriott International. The hotel chain took a chance on the remote location, a 20-minute boat ride from St. Mark’s Square.

The artificial island was built in the 1860s to store fuel and other combustibles but soon became, like the much older neighboring islands, a sanctuary for convalescents. In the 1890s, owing to the island’s proximity to the sea, its agreeable climate, and distance from the cramped quarters and pollution of the city, many of the buildings on its 40 acres were converted to hospitals to treat pulmonary ailments. By the 1930s, a large modern medical facility had opened, to much national fanfare.

That sanitarium would continue to treat patients for five decades, but eventually the entire island was vacated, and it sat in ruin, until the start of a restoration in 2000. That project, taken over by the Milan-based firm Matteo Thun & Partners following an invited competition in 2011, transformed the five-story main hospital building and 17 other smaller ones into 266 hotel rooms and suites, three restaurants, several bars, and a spa. “When you arrive on the island from Venice, you come from a totally urban situation, with no green spaces and overrun with tourists,” explains Matteo Thun. “We wanted to create a 360-degree alternative with a resort experience.”

The architecture of the main building expresses the abstract geometry of prewar Italian Rationalism, where function prevails over aesthetics. “The top of the building looks like a de Chirico painting,” Thun says. “We wanted to follow that Rationalism.” Thun and his partner Luca Colombo left the floor plans largely intact, keeping the wide corridors and their large glass doors onto the terraces of the original hospital. The interiors are mainly white, like the exterior stucco, giving the entire building a light, airy feel. Public spaces are outfitted with lighting that Thun—also well known as a product designer—created for a couple of Italian brands. The biggest architectural intervention was on the roof, where an infinity pool was added beside the rooftop bar and restaurant. Bounded by a glass parapet, the heated water of the pool seems to merge with the lagoon, while views of the cupolas of St. Mark’s Basilica and its neighboring campanile are visible beyond.

Slightly more upscale suites with a colorful décor were designed for the smaller, older buildings, which, while not historically significant, were handled with, so to speak, pres­erva­tionists’ gloves. “The broken brick walls are very similar to what you see throughout Venice, consumed with the patina of salt and wind,” says Thun. “We did not want to touch them from the outside or from the inside.” For several of these former warehouses, now sporting such names as La Maisonette and La Residenza, the architects employed a “box in a box” approach, inserting a steel structure several feet away from the masonry shell. In the spa building, they added a metal grid—an architectural feature commonly used in Medieval Venice and made popular again by Carlo Scarpa—over parts of the facade to act as both a privacy and sun screen.

The gardens and landscaping on the island, today commonly referred to as Isola delle Rose (Island of the Roses), are as prominent a feature as the architecture. Stately olive trees that border the many allées are harvested to provide the olive oil used in the informal cooking school and restaurants, including the Michelin-starred Dopolavoro. Meaning “after work,” Dopolavoro takes its name from the building in which it is housed, a 1936 structure with hints of a classical vocabulary built for doctors and nurses as a place to eat, drink, and watch movies following their shifts. Newly planted herb and vegetable gardens also contribute to the restaurants’ menus.

The architects were frankly skeptical that travelers to Venice would want to stay so far from the action of the city itself, but since opening in the spring of 2015, the seasonal hotel has frequently been at capacity. A more affordable alternative to Cipriani—also removed from the throngs of tourists on an island closer in—it is especially popular with families, as children can safely run about. For adults of today, including this one, the seclusion of the small island, with its cheerful spaces, does not feel imposed but, rather, welcome.
