Heritage Day in Berlin
Explore hidden secret spaces only accessible to experts and curious curators – the “Day of the open Monument” see the (free for many) entry into private city monuments. This is more or less an invitation to go where you’re not usually allowed and have a poke around, or the most civilized version of urban exploration available.
You can get a glimpse at usually private churches, Jewish “stolen land” and hidden graveyards inside old schools. There are stories everywhere, so why not open up Berlin and see what you can find? You can’t get much more off the beaten track.
