Gibraltar is home to large groups of Barbary macaques, sometimes referred to as “Gibraltar Monkeys”. It is the only wild population of monkeys in Europe.
Nobody knows exactly why there are monkeys in this part of the world, but they have been there since before it became a British Overseas Territory in 1713.
While they attract curious tourists, it is strictly illegal to feed the Barbary macaques and you should avoid interacting with them in any way. Keep a safe distance between you and the monkeys as they can be aggressive and steal food and belongings.
