The new museum has seven rooms.
The first three tell the story of the convent, from its creation to the early 20th century.
The next three are dedicated to the life and work of Mother Margarita María.
The last covers the missionary activities of the congregation of the Mercedarian Missionaries of Berriz, particularly during the last fifty years.
They are illustrated with photographs, films, magazines, books, documents, art works and a variety of other objects linked to the life and activities of the convent.
