What is the Heidelberg outdoor escape game?
The Heidelberg outdoor escape game is an escape room with the roof taken off: a puzzle is hidden at each of the city's landmarks, you open it on your phone and you solve it by observing what is actually there and reasoning from it. Allow roughly 2 hours, of which only 30 minutes are spent walking the 3 km that link the 10 stops.
Puzzles wait at the Old Bridge over the Neckar and at the bronze monkey beside it, on the Marktplatz in front of the Church of the Holy Spirit, at the Jesuit Church of red sandstone and on Universitätsplatz, where a university has stood since 1386. Each one stands alone, with no storyline running between them, and three levels of hints are there when one holds out. The old town makes it easy: it is small, largely pedestrianised and the castle ruins stay in view.

What you do on the escape game
Solve on the spot
Work out each puzzle from the landmark in front of you. No prior knowledge of Heidelberg is expected.
Look for the detail
Clues hide in the red sandstone façades, the statues, the inscriptions and the shape of each square.
Walk a little
Google Maps links the stops: just 30 minutes of walking across 3 km in total.
No clock
Nothing counts down. Take a hint if you want one, break for a drink in the old town and finish later or another day.

Puzzle route: from Bismarckplatz to Karlsplatz
10 stops · about 30 min walking · start: Bismarckplatz park · finish: Karlsplatz
Puzzle one is in the small park on Bismarckplatz, at the western end of the old town, and the last one is on Karlsplatz below the castle. On the way you work through the Haus zum Riesen, the Palatinate Museum, Universitätsplatz, the Jesuit Church, the Marktplatz, the Brückenaffe, the Old Bridge and Kornmarkt. Starting in daylight is better, since the puzzles are read off the buildings themselves and rain or wind makes that slower. Google Maps covers the short hops, the app lets you reorder the stops, and nothing on the route needs an entry ticket.

1Bismarckplatz parkStart
The small park on Bismarckplatz lies at the western edge of the old town, next to Heidelberg's busiest tram and bus interchange. The square is named after Otto von Bismarck, the first chancellor of the German Empire, and from here Hauptstraße, one of the longest pedestrian streets in Germany, runs east into the old town.
2Haus zum Riesen
This baroque mansion on Hauptstraße was built in the early 18th century, when Heidelberg was rebuilt after the French destruction of the 1690s. According to tradition its builder used stones from the castle's Thick Tower, which French troops had blown up, and the house is named after the larger-than-life statue on its façade.
3Palatinate Museum (Kurpfälzisches Museum)
Heidelberg's museum of art and history occupies the Palais Morass, a baroque town palace built in the early 18th century for a law professor of the university. Its collections include Tilman Riemenschneider's carved Twelve Apostles Altar and a cast of the jaw of Homo heidelbergensis, found near Heidelberg in 1907.
4Universitätsplatz
Heidelberg University, founded in 1386 by Elector Rupert I, is the oldest university in today's Germany. On this square stand the baroque Old University and the New University of 1931, built largely with American donations and inscribed with the words Dem lebendigen Geist, to the living spirit, and a lion fountain.
5Jesuit Church
The Jesuit Church was begun in 1712, at a time when the Catholic electors of the Palatinate were strengthening the Catholic faith in Heidelberg. Its tall façade of red Neckar sandstone faces a quiet square in the university quarter, while the bell tower was only added in the 19th century.

6Marktplatz (Market Square)
The market square is dominated by the Gothic Church of the Holy Spirit, burial place of the Palatinate electors, which for more than two centuries was divided by a wall between Protestants and Catholics. Small shops are built between its buttresses, and opposite stands the Haus zum Ritter of 1592, one of the few houses to survive the fires of 1693.
7Brückenaffe (Bridge Monkey)
This bronze monkey by the sculptor Gernot Rumpf has sat beside the old-town end of the Old Bridge since 1979. It recalls a stone monkey that once stood on the medieval bridge tower. Local tradition says that touching its mirror brings wealth and touching its fingers means you will return to Heidelberg.

8Old Bridge
The Old Bridge, officially the Karl Theodor Bridge, was built of stone between 1786 and 1788 under Elector Charles Theodore, after ice had destroyed the wooden bridge before it. Its bridge gate with two white towers was part of the medieval town wall. German troops blew up the bridge in 1945, and it was rebuilt by 1947.

9Kornmarkt
The former grain market below the castle is centred on a baroque statue of the Virgin Mary from the early 18th century, set up as a sign of the Catholic Counter-Reformation. From the square you get a classic view up to the castle ruins, and the lower station of the funicular to the castle is close by.
10KarlsplatzFinish
This wide square at the eastern end of Hauptstraße lies directly below the castle and offers one of the best views of its ruins from the old town. On one side stands the Palais Boisserée, where the brothers Sulpiz and Melchior Boisserée showed their famous collection of old German paintings in the early 19th century.
