Casa del Libro

The 18th-century mansion known as Casa del Libro houses a vast collection of rare sketches, illustrations, ancient manuscripts and books, some dating from before the 16th century. The museum's most prized possessions are two royal mandates signed by Ferdinand and Isabella of Spain in 1493 regarding the provisioning of Christopher Columbus's fleet for his second voyage to the New World. This was the voyage during which Puerto Rico was discovered.
