One of the best ways to discover the past of the island is visiting the Painted Cave in Galdar. This Museum and Archeological Park was discovered in the 19th century by a local farmer and it shows various types of pictures from the pre-Hispanic times from the ancient citizens of the island. They need 24 years to work on the excavations and on the preservation of this archeological site, which is a very important witness of the aboriginal life. The building of the actual museum is located on the archeological remains of a village and its visit is a good way to know how the indigenous houses and caves were. It is a magnificent visit to learn about the past of Gran Canaria.
