Completed in 1416, the interior of the Church of St. Clara was transformed by impassioned 17th-century artists, masters of woodwork and gilding. Nearly every square inch is covered with carved and gilded woodwork depicting angels, saints, cherubs, and patterned designs in an architectural mélange of rococo and baroque, one of the most exceptional examples in Portugal. The clerestory windows permit the sun to flood in, making a golden crown of the upper regions. In deliberate contrast, the building's facade is squat and plain. If the keeper of the keys takes a liking to you, he'll lead you on a behind-the-scenes tour of the precincts. In the Tribute Room, for example, he'll point out a devil carved on the choir stalls.
