The most popular cities in the world are often instantly recognisable thanks to their world-famous landmarks. But what would these cities look like if they did not have their prized attractions? That's what one studio asked its designers, and the images it received back were certainly illuminating. Scroll down for video . Without the 324m-high Eiffel Tower in Paris, the skyline looks incredibly bare and dark, which is not surprising considering it has 336 lamps illuminating it at night . The iconic tower, on the Champ de Mars, was opened in 1889 and has come to define the French capital . The Arc De Triomphe was constructed in 1806, and is the centrepiece of Place Charles de Gaulle at the end of the Champs-Élysées . The imposing monument celebrates France's military glories and also its military heroes - tourists can climb up tot the roof for beautiful views of Paris . Virtual studio DesignCrowd invited people to submit before and after graphics of some of the most well known landscapes as we have never seen them before. Nearly 100 submissions have been created, with a number of them focusing on the 300m-high Eiffel Tower in their creations . The startling absence of the giant tower left the landscape feeling bare and flat, although it did allow for views from the Trocadéro Gardens, through to the Champ de Mars. More missing features in Paris included the impressive Arc De Triomphe. Instead of leading to the famous centrepiece, the multiple surrounding roads meet at a bare, round circle. Without the Statue of Liberty to draw boats of tourists, Liberty Island looks forlorn and barren. All that remains of the island is the paved stone where the iconic colossal neoclassical sculpture stood. The Statue of Liberty draws boats of tourists every day, but without the iconic lady, Liberty Island looks nothing special . Siena Cathedral is a medieval church in Siena, Italy that has been around since 1215. Its spires and towers peek over the city . The River Thames looks just like any other river with the elegant Tower Bridge stretching across the waterway . The iconic Tower Bridge is featured in nearly every London tourist shop and often mistakenly referred to by visitors as London Bridge . Designers imaged what London would look like without its most photographed clocktower and Westminster Palace . The Palace of Westminster is more commonly known as the Houses of Parliament, with both the House of Commons and House of Lords based in the Gothic-style waterfront building . London's attractions draw millions of tourists every year, but there would be a lot less photographs taken in the city if Big Ben was not a feature on the skyline. It is said to be the most photographed clock in the world, and would not be easy to remove, sitting at over 13 tons. The sunset skyline looks empty without the impressive architecture of the Palace of Westminster. The banks of River Yamuna, in Agra, look desolate with the majestic presence of the Taj Mahal . The Taj Mahal is a striking white marble mausoleum in Agra, and brings millions of tourists to the surrounding area . A certain Holy presence is missing from the skyline of Rio de Janeiro, making the normally instantly-recognisable city a little more mysterious . Christ the Redeemer overlooks all the goings on in Rio, and makes the city instantly recognisable . The Sydney Harbour stands out due to its uniquely designed opera house, which resembles the sails of a ship, without it the skyline looks like any other cluster of skyscrapers . The beautiful monastery carved out of red rock in Petra, Jordan, was originally part of a Nabataean . The rose-red Petra is Jordan's most prized tourist attraction, and hopefully, being a UNESCO World Heritage Site, will never disappear . Machu Picchu was only rediscovered by western travellers in 1911, leading to the site being excavated and becoming a tourist attraction . The ruins at the Inca settlement of Machu Picchu in Peru have made the area a bucket list favourite . Niagara Falls without the falls is a dry, barren hole, and would not attract the 12 million annual visitors it does today . On the border of the US and Canada, Niagara Falls is actually made up of three separate waterfalls . The designs also featured landmarks outside of typical city backdrops. Without the tumbling 51-metre-high Niagara Falls, the area left behind would not pull the 12 million annual visitors that it sees every year. While the Andes are an incredible sight by themselves, iconic pictures with the ruins at the Incan settlement of Machu Picchu, have made the area a bucket list favourite. Standing at 68m, the Obelisk of Buenos Aires would be missed from the urban landscape behind if it were removed . The Four Face Sculptures of late Presidents on Mount Rushmore have vanished, leaving behind just another normal rockface . Mount Rushmore would be unrecognisable without the presidential presence which has been in place since the carvings were completed between 1934 and 1939 .
