Part of the World Heritage Site by UNESCO, this quinta (manor house) in the old quarter was built at the turn of the 20th century. It incorporates architectural elements of the Gothic, Manueline, and Renaissance styles. When you tour of the property, you’ll see its antiques and artifacts, but, more interesting hear about the owner, a Brazilian mining mogul who was obsessed with the Knights Templar and Freemasonry. Many of the elements in the house and garden are linked to those interests, including the bizarre 100-foot deep “initiation well” (it’s an upside-down, underground tower). The building’s turrets afford panoramic views of the countryside.
