Billed as “a time-travel through more than 2000 years of history,” Paris 3D provides a virtual tour of many of the landmarks of Paris and lets you see how the city has developed since its Roman conquest in 52 BCE right up to the present day. Users can take guided tours from the 3D Paris website or on the accompanying iPad app. The site and the app are both free. Through the website, you can witness the construction of the Bastille and Notre Dame, navigate through winding stone streets in the Middle Ages and visit the 1889 World’s Fair to see the appearance of the Eiffel Tower. The Paris 3D website has been painstakingly built over two years by a team at Dassault Systemes, and they will continue to add more buildings and items over the coming years, again all free. Many of the monuments, such as the Bastille, no longer exist in the real world, so this site offers a great way to explore them as they would have looked
