The Gunpowder Garden was called by this name because of the presence of the royal factory of gunpowder and salt in it at the beginning of the seventeenth century, which was considered the only Spanish factory that supplied gunpowder and lead to fighters during the War of Independence. General, it has many distinctive features where the Spanish Arab gardens have been recreated with a fountain with three types of arches symbolizing the three cultures that coexisted in the Segura Valley.
