Built between 2584 BC and 2561 BC, the Great Pyramid of Giza is the only surviving ancient wonder. It is 230.4 metres wide at its base and 146.5 metres tall, and is the largest of three that sit beside the city of Giza, around 12 miles from Cairo. It was the tallest man-made structure for more than 3,800 years, until the completion of Lincoln Cathedral around the year 1300.
The modern alternative? Modern pyramids include the glass entrance to the Louvre in Paris, the Walter Pyramid in Long Beach, California, and the 30-storey Luxor Hotel in Las Vegas. The world’s tallest pyramid-shaped structure is the colossal Ryugyong Hotel in Pyongyang, North Korea – dubbed the “Hotel of Doom” – at 330 metres tall. It is followed closely by The Shard in London (309.6m).
