It's an indoor market, which makes it a great option in winter if you are looking for anything from kitsch to classy. I like it because you find lots of old objects that transport you to the past.
25 years ago my father used to work here. I know they have a garden on top of the roof. It looks like a big spaceship, I love the futuristic design it has so many little details, I never get tired looking at it.
It is the connection between Leinestrasse u-Bahn and Tempelofer Feld. The park is wild and quiet, and super relaxing :) it is nice to sit on a bench and do some people-watching: it is a big inspiration for illustrators!
One of the most beautiful pieces of Berlin actually is a piece of another city (Al-Hillah, Iraq). Normally Berliners are laid back and like to hang around, drink beer and chat till sunrise. Sometimes they do get excited though, and then they start taking old war-battered stones and piecing them together to (re)form walls. The results are great as can be seen all over Berlin, but the Ishtar gate in the Pergamon museum is where they’ve really outdone themselves.
