Here are a few more places — and a bit about each — from my exploring in Berlin. The best way to see this city is on foot; it doesn't perform for you, it just lets you walk up to history and look at it.
I started at the wall. The East Side Gallery is the longest surviving stretch, turned into an open-air gallery of murals — paint layered directly over the concrete that once split a city. Art on the wall itself felt like the right way for it to stand now.
Then Berlin Cathedral on Museum Island — big, sandstone, and impossible to miss from across the Spree. The city rebuilt it, stone by stone, after the war. Berlin has had a lot of practice at rebuilding.
Checkpoint Charlie — the old crossing point between East and West. It's touristy now, but stand there long enough and the weight of it settles in: people risked their lives to get across a line that ran right through this street.
And the Fernsehturm — the TV tower that shows up in half the photos of this city. It's a handy compass: no matter where you wander, you look up, find the sphere, and know which way is home.
Until the next run out — work hard, play hard.
