HOW TO USE A VIRTUAL WALK: 1. Click on the thumbnails of locators / markers, which are marked directly on the walk. 2. We can navigate between panoramas by clicking the thumbnails at the bottom of the screen (some of them contain several panoramas from which we can select a specific fragment). 3. Open the map on the right side of the screen (small map icon). Thanks to this option, we are able to move around the virtual walk, knowing the exact location of particular places. 4. Panoramas can be zoomed in and out by using a computer mouse.
