How to use this tour
In each section of the tour, you’ll see either a sequence of photographs, like here, or a panoramic image that you can drag with your finger to look right round the scene.
With both photographs and panoramas, you can use your thumb and finger on the screen to zoom in and see more detail.
In many places you'll see a “Points of Interest” button that shows highlights you can explore.
