Download the tour, pop your phone in your pocket, and let this enthusiastic Heidelberger resident take you around the town she loves.

The center of the Altstadt, the Marktplatz, or Market Square, is where you can sit outside in the summer and enjoy a coffee, or a Glühwein in December at our gorgeous Christmas Market. There’s a lot of history in this square, and we’ll do a full circle on the audio tour.

The Alte Brücke, or Old Bridge, is a bit of a misnomer. Built in 1877, it’s quite young compared to the rest of Heidelberg. Depending on who you ask, it’s either the 11th or the eighth bridge on that spot. Floods are a common experience in Heidelberg’s history, and if you know where to look, you can find the marker for the highest flood ever to hit the town.

The Student Prison, or Student Karzer was an important part of student life for over 135 years, from 1778 to 1914. No, students weren’t put in prison for bad marks, but what they did get up to was driving the town residents crazy. So much so, the phrase ‘letting the pigs loose’ in German is a local idiom for getting drunk and rowdy.

This square has been a meeting place for Heidelbergers since the 1500s, but the name Kornmarkt only came about in the 1600s. The red stone and white building here is a side of the Stadthalle, or the City Hall.

A landmark in Heidelberg, this church holds the keys to some fascinating stories about our historic town. Why are there doors halfway down the building? Have the shops under the eaves always been there? Find out more as we circle the building in the audio tour.

Jesuitenkirche is the main Catholic church in Heidelberg. The variegated red stone is from the Neckar valley quarries, and it practically lights up from within in the evening light. The construction began in 1712, and finally finished with the addition of the tower in 1872.

The Castle is located only halfway up the hill. You can take the old funicular, with its 100-year-old wooden carriages, up the last leg to the summit. There are incredible views over the city, many nature trails, a falconry open to visitors, and a small amusement park for children. You can, of course, make the climb yourself.
