Steeples, spires, columns, pillars...towers! Free-standing or part of larger structures, towers are not only some of the most popular sites to visit, they're some of the most well-known icons in the world.
During our Jamboree in Prague we had a hackathon where Ionut looked at Instagram tags and what they tell us. The above images shows us where most pictures are tagged with #tower around the world.
From the Eiffel Tower to the leaning tower of Pisa, the Petronas Towers and the Kuala Lumpur Tower to the Tokyo Skytree, and of course the current record-holder for the tallest building in the world - the Burj Khalifa in Dubai. These structures are just some of the many that 'tower' over the rest! Whether you like to go to great heights and photograph a bird's eye view or look up from below and gaze into the clouds, check out our heatmap to see other popular towers around the world.
