Casita Museo de Ratón Pérez

Ratoncito Pérez was created in the 19th Century by Friar Luis Coloma, a Jesuit who was a Royal Counsellor at the time, and was one day commissioned to write a story for little Alfonso XIII, when one of his milk teeth fell out at the age of 8. The story was about a mouse that lived with his family in a box of biscuits, kept in a confectioner’s warehouse near the Royal Palace. According to the story Ratoncito Pérez visited the bedrooms of the future King and of other poorer children.

This is the origin of the character who visits children and leaves them a present in exchange for every tooth they lose. The Museum is located in the place where the loveable mouse used to live with his family, according to the story. It has two small areas where children and adults can learn first-hand about the house the mouse used to live in, look at historical documentation on the character, and see milk teeth that belonged to celebrities like Beatrix Potter, Beethoven, Isaac Newton, and Rosalía de Castro. Suitable for children of 5 and above.
