Built in the mid-13th century, the Church of São Tiago and Cabrais Chapel are an important testimony of the late Romanesque in Beira Interior. Inside, one can observe a granite Pietá and wall paintings from at least two eras, and one can find traces of a triptych built by figures representing Our Lady, St. James (orago) and St. Peter. The Cabrais Chapel, or Cabrais Pantheon, is where the tombs of several members of the Cabral family are, such as the tombs of Pedro Álvares Cabral's parents.

It is an authentic monumental space where it is important to highlight the old walls, the ruins of the Palace of Cristóvão de Moura, the five hundred year old pillory, the main church, the medieval cistern and the vestiges that confirm the existence of New Christians.

The Museum of Guarda opened to the public in 1985 and its collection is made up of collections of archaeology, numismatics, sacred sculpture from the 13th to 18th centuries, sacred painting from the 16th to 18th centuries and armoury from the 17th to 20th centuries. There are also ceramics, photography, regional ethnography, painting and drawing from the end of the 19th century and the first half of the 20th century.

With a privileged location, in the heart of the city of Guarda, it is therefore an emblematic building, with a strong symbolic identity in the urban surroundings, thus assuming preponderance in a vast commercial, cultural and leisure area.
