Alameda Gardens presents a strange mélange of botanical and military information about Gibraltar. While you wander among 200-year-old dragon trees and stone pines and rare native plants, keep an eye out for guns, mortars and howitzers, too. These guns, and memorials to General George A. Eliott and the Duke of Wellington, remind visitors of the long military presence here. Displays in the restored 17th-century stone cottage explore the history of the gardens.
