Open since 1986 this cool little bookstore has an awesome collection of rare and interesting books and is spread over many floors. It houses way more books than it looks like it was from the outside and has a really quaint and cozy bookstore vibe. The staff was also very polite and we were able to find some really interesting titles. As you would guess most of the titles are in German, but I was able to find many English versions as well. It's free to enter and I believe this is a must visit while in Heidelberg, especially for any reading fans. read more
They even had a whole bunch of VERY OLD books in English. Under the big table on the left side; three shelves - and more books behind those.
Reasonable too.
Minus one star because they're very very dusty. My eyes were itchy after. read more
