The Rock of Gibraltar
Gibraltar (UK)
The Rock of Gibraltar is a striking monolithic limestone mountain rising 426 meters above sea level, located at the southern tip of the British territory of Gibraltar. It dominates the western entrance to the Mediterranean Sea and is part of a narrow 9-kilometer promontory extending southwards. Historically known as Mons Calpe, it is one of the ancient Pillars of Hercules, marking the edge of the known world in classical mythology. The Rock features a complex network of man-made tunnels known as the Tunnels of Gibraltar, reflecting its strategic military importance. Its upper areas are designated as a nature reserve, home to around 300 Barbary macaques, Europe's only wild monkey population. Geologically, it is composed mainly of Early Jurassic limestone and dolomite, with layers of shale and sandstone, bearing marine fossils that reveal its ancient origins. The Rock's current form was shaped by tectonic collisions and sea level changes about 5 million years ago, contributing to the creation of the Mediterranean Sea. Today, it is a major tourist attraction offering panoramic views, rich natural heritage, and a glimpse into its military and geological past.
ヒント: The best time to visit The Rock of Gibraltar is during the spring and autumn months when the weather is mild and the nature reserve is vibrant. Visitors are advised to purchase tickets for guided tours of the tunnels in advance, especially during peak tourist seasons. Discounts may be available for seniors, students, and families. Wearing comfortable walking shoes is recommended due to the rocky terrain and extensive walking paths. Check opening hours ahead as they can vary seasonally.
