The Berlin Wall app is a companion for the website chronik-der-mauer.de. This is an online project that shows the exact course of the former Berlin Wall. On the website, you can find the information on the exact location of the wall and also view the images and texts that are available at the respective location. If you want to know more about the sites and locations, you can download the data package for free.

To use the app, you need an internet connection. It also requires the authorization to store data (for additional tours and downloaded POI data packages). The map is interactive and can be zoomed in and out.
