Heidelberg's Altstadt: A Self-Guided Audio Tour

Join Heidelberg resident Erin McGann on a winding self-guided audio tour of the picturesque Altstadt, the old town of this fascinating German city on the banks of the Neckar River.  Take in the famous Church of the Holy Ghost in the center of the main market square, discover the carvings that allowed residents to check the legal size of their pretzels (really!), hear stories of the catastrophic floods, find out which buildings are the oldest, hear how the university students got so rowdy they ended up with their own prison, and learn about the romantic history of our ruined castle.  The tour is ready whenever you are and the audio plays automatically at exactly the right time and place using your smartphone's GPS and the VoiceMap mobile app, which also works offline.
