Ágreda is a municipality located in the province of Soria, in the autonomous community of Castile and León, Spain.

During the Middle Ages Ágreda became more significant as a strategic border location between the kingdoms of Castile and Aragon, as well as an important center of the arts and handcrafts where Christians, Jews and Arab-descendants lived in peace.

She was named a Venerable of the Roman Catholic Church shortly after her death in 1665, but has not yet been beatified or officially canonized as a saint.

She was well known as a visionary of her times, and as a counselor to King Philip IV through a correspondence that lasted throughout each of their lifetimes and is documented in over six hundred letters between them.

Over the years the king gave the abbess a few commemorative gifts [2] which are on display today in the convent, yet there seems to be no undue favoritism to the region because of their friendship.
