In page Angueira:

"

In addition to the religious architecture, Angueira still preserves examples of the castro culture, which at one time supported the Moors, or pre-dates their period.[1] In addition, springs, such as the Fonte Santa, known for local healing properties or "miracles" that may have occurred from the fresh waters.[1] The local government has gone so far as to requalify the area around Fonta Santa, in order to attract further eco-friendly investments in the area.[1] Related to these changes has also been the attempted preservation of local grist mills; yet, issues associated with local property rights have made attempts for full conservation complicated.[1]
