Pillars of Hercules - According to Greek mythology, Hercules was tasked with twelve labors, one of which was to bring the cattle of Geryon from the west to Eurytheus. During his journey, Hercules had to cross the Atlas Mountains. Instead of climbing over them, he used his immense strength to break through, connecting the Mediterranean Sea and the Atlantic Ocean. This feat resulted in what is now known as The Pillars of Hercules, comprising the Rock of Gibraltar on the northern side and Jebel Musa in Ceuta on the southern side.

St. Michael’s Cave - Among the over 150 caves discovered in the Rock of Gibraltar, St. Michael’s Cave is the most visited, attracting over one million visitors annually.

Barbary macaque feeding station - Located at the top of the Rock, this stop offers breathtaking views of Gibraltar. Visitors can interact with the famous Barbary macaques at Upper Apes Den, situated at the same height as the cable car. These macaques are the only ones found in Europe and reside in the Upper Rock Nature Reserve of Gibraltar. Currently, there are over 200 macaques in 9 groups roaming the upper rock. Legend has it that in 1942, the macaque population dwindled to just 7, prompting British Prime Minister Sir Winston Churchill to order their immediate replenishment, as the presence of Barbary macaques on the Rock of Gibraltar is believed to ensure British rule.

Gibraltar: A City Under Siege Exhibition - The City Under Siege Exhibition is housed in buildings that are likely among the first constructed by the British in Gibraltar, dating back to the early 18th century. A notable feature of these buildings is the graffiti on the walls, created by soldiers on guard duty to stay awake during long hours, as falling asleep was punishable by death at that time.
-
The Great Siege Tunnels - The Great Siege Tunnels are a major attraction in the Rock of Gibraltar. These tunnels were manually carved out of the rock during the Great Siege from 1779 to 1783 to defend Gibraltar against Spanish and French forces attempting to reclaim it from the British. During the tunneling, a horizontal hole was blasted in the rock face to improve ventilation for the workers, and it was realized that a gun could be positioned to target attacking forces.
