Discover the famous “Crystal Palace” in stunning detail through augmented reality (AR). You can use this app at the site of the Great Exhibition of 1851, on the south side of London’s Hyde Park, to walk around the ground floor of the building at its full scale and in the original location. Alternatively, open it in any large open space to view the building at its original size, or scale it down to sit on your table at home. However you view it, this app will bring a marvel of its day spectacularly back to life.
