Germany

Heidelberg, Germany connects to 5406 places across 27 topics through 1476 Bunkabop connections, with science as the dominant thread. The city's university ties pull strong overlaps with Berlin, the United States, London, and Oxford. Its cultural reach extends to art, literature, and history: Luther's 1518 disputation here helped shape the Reformation, and the 1970 World Science Fiction Convention chose Heidelberg as the first non-English-speaking host city in the event's history.
