Hotel Monasterio in Cuzco, Peru

Among the oldest of the religious buildings in the Americas adapted into a hotel is the Hotel Monasterio, a Spanish former monastery dating from 1592. It sits in the heart of Cuzco, the ancient capital of the Inca empire, off the city's central square.

Now an Orient Express hotel, the 126 rooms are awash in buttery, neutral tones, the walls adorned with religious colonial art. Many of the rooms overlook Cuzco's central square, just steps from other colonial and Inca monuments. At 11,000 feet above sea level, unique to the hotel are oxygen-enriched rooms to help visitors adjust to the thin air. Hotel staff can arrange Orient Express train transport to the Lost City of the Incas, Machu Picchu, where the company's sister property sits at the entrance to the historic ruins.

Sofitel Santa Clara in Cartagena, Colombia

This Sofitel began its life as a monastery in 1621 in the Spanish colonial city of Cartagena de Indias, one of the best-preserved colonial cities on the South American continent. The city was declared a UNESCO monument in 1984. The monastery was part of the setting for Colombian author Gabriel Garcia Marquez's magical realism novel "Of Love and Other Demons."

Today, a new fantasy is born with 119 rooms, 17 of them suites, in the old monastery and the new extension. The décor mixes ancient walls with modern touches and conveniences. The interior courtyard houses an outdoor pool, and the spa is equipped with a hammam, Jacuzzi and solarium. During the renovation of the hotel, many colonial artifacts were uncovered, and they are now on view throughout the hotel. Colonial Cartagena is itself a living museum, all within walking distance of the hotel.

Ratna Ling Spiritual Retreat on California's Sonoma Coast

There's no need to leave the United States for a relaxing religious retreat. In Northern California's Sonoma County, you'll find the misty fog-covered Ratna Ling Buddhist retreat tucked away on a redwood-forested ridge just a few miles from the Pacific coast. Though not a monastery, the retreat follows the nyingma traditions of Tibetan Buddhism. All meals are strictly vegetarian.

Guests don't have to be Buddhist but simply seeking out "a quiet natural beautiful place to experience what it is like to be without distraction, and get a sense of your own breath, eating mindfully, applying attention to your own steps, applying attention to your own balance," retreat manager Chelsea Rappel said. With a printing press on site, guests can also learn ancient Tibetan book-binding processes.

The retreat is about a 2½-hour drive from the Golden Gate Bridge. Some visitors come for the day, but overnight visits are encouraged.

Park Hall Country House in Clacton-on-Sea, Essex, England

Medieval mystery and history are part of a vacation at the Park Hall Country House, a former monastery dating to 1360, though it's believed to have been built over an earlier structure. The recorded history of the land dates to 1016. During renovations of the property, false walls were uncovered that led to the discovery of Middle Age paintings, including one of the Virgin Mary surrounded by Latin prayers, seated on a throne. Other treasures on site include urns commissioned by King Henry VIII.

Today, the hotel is surrounded by extensive gardens and farmland, and only a few minutes drive from the Essex seacoast. It's about an hour and a half northeast of central London. Guests can stay in the main house in antique-filled spaces like the romantic Bishop's Room, a favorite of newlyweds, or in scattered cottages and buildings on the grounds. One of these buildings, the Cart Lodge and Hay Barn, features a soaring half-timbered loft space, giving a true medieval feel.

Hotel Klosterbräu in Seefeld in Tirol, Austria

Portions of the 100-room Hotel Klosterbräu date back more than 450 years to its former life as a monastery. A new five-star luxury hotel has been built within the grounds of the complex in a traditional Alpine style.

The town of Seefeld is one of Austria's most popular resorts, about a half-hour from the Innsbruck airport. The bucolic mountain setting gives the property a "Sound of Music" sensibility. The hotel can arrange tennis and golf outings at nearby venues, and for ski buffs, an adjacent ski resort is a five-minute walk away.

The newest part of the hotel is the 4,000-plus-square-meter Spiritual Spa, which takes cues from the site's history as a monastery and the rituals of the monks who once lived here.

The spa's themes are ruled by what the resort calls "10 pillars of contemplation" such as health through fire, which involves hot saunas and open fireplaces, or health through stone, using stones and crystals for massage therapy. Best of all is the Augustinian Beer Bath, where guests are doused in beer while drinking a glass.
