A great way to get some exercise in these times of lockdown is a walk through our beautiful city. And from now on, you can make that walk a lot more interesting! The Dwaalspoor-app by advertising agency Everybody Likes Penguins lets you stroll through town while discovering some of the history of the stately buildings and ancient tress you pass along the way. The quest starts at the Domplein square, where you will dive into the past with the first photo. Do you recognise the picture in the current view? Then just follow the route with the rest of the photographs. When you recognise something from these photographs, you simply walk in that direction. The accompanying text for each picture provides interesting anecdotes or a useful clue to find you way.
