Chase The Third Man? While Carol Reed's classic post-war film noir actually takes place in Vienna, you can recreate its dark atmosphere by taking a guided tour of Basel's underground sewerage system (don't worry, this being Switzerland, it's not overly smelly). After entering a tunnel at Heuwaage, you follow the Birsig river underground to its estuary in the Rhine. The 1 hour 15 min tour ends at Restaurant Safran-Zunft in the city center, where you are taken up into the light again - and to tasty snacks. The tour requires a group to justify the somewhat high cost of Fr. 250 (per group, not person); you should either find like-minded folks or try to join an existing group. Contact the urban planning firm Lindenberg 3, +41 61 683 56 52, for details and reservation.
Basel Minster
Now a Reformed Protestant cathedral, it was built from 1019, badly damaged in an earthquake of 1356, and completed in 1500 in Romanesque & Gothic style. The Galluspforte (Gallus portal) on the western façade is a magnificent sculptural work. Figures carved on the main (south) façade include St. George slaying the Dragon. Inside, there's a sandstone lectern, and a crypt with tombs of early bishops of Basel; also buried here is Jacob Bernoulli, who discovered the mathematical constant e. You can climb either or both towers: St. Martin's is 62 m and St. George's is 65 m.
Protestant church completed in 1864 in neo-Gothic Revival style. Note the stone pulpit with wooden canopy.
