The story that haunts this land
Your investigation begins at the Gerechtigkeitsbrunnen, the Fountain of Justice on Marktgasse. Erected in 1545-1546 by Hans Rudolf Manuel Deutsch, this 5-meter-high fountain, a historic monument since 1854, depicts Justice trampling a tyrant. The central winged female figure holds a sword and scales, symbolizing Bern's uncompromising justice in the 16th century. This ensemble is one of the 11 fountains in the old town and serves as the first clue to understanding the foundations of Bernese authority, a key element in deciphering Lucy's code, immersing you in the history of Bern.
Continue your journey to the Kornhaus, a former grain warehouse built between 1668 and 1674 by Joseph Abeille and Samuel Caussanel on Kramgasse. This historic monument, listed in 1961, could initially store 10,000 tons of grain. The frescoes on its facade, painted in 1684 by Wygant, illustrate agricultural and allegorical scenes, offering you a glimpse into Bern's economic life. Used as a communal silo until 1882, it was transformed into a restaurant and concert hall in 1925, showing the evolution and adaptation of the UNESCO World Heritage of Bern. This stop is crucial for your visit to Bern.
The Einsteinhaus, at Kramgasse 49, is your next stop. It was in this 90 m² apartment that Albert Einstein lived from 1903 to 1905 and conceived the theory of special relativity in 1905, a scientific breakthrough that changed the world. His daughter Lieserl was born here in January 1904. Listed as a historic monument in 1979 and open to the public since 1977, this place is a direct testament to human ingenuity. By exploring this apartment-museum, you will discover clues related to Einstein's thought, essential leads to understanding the complex mechanisms of Lucy's transmitter and the history of Bern.
Then cross the Nydeggbrücke, a 172-meter-long sandstone bridge, built in 1843-1844 by Ferdinand Kurmann. It replaced a medieval wooden bridge from 1265 and connects the old town to the Aare. This bridge, which withstood the floods of 1876 and 1910, is an architectural element of Bern's UNESCO zone. It offers a view of the medieval towers of Nydegg, dating from 1461. As you cross, you will perceive how architecture and engineering shaped Bern's urban landscape, crucial visual clues for your GPS treasure hunt.
Your journey concludes at Bärenplatz, a historic square formed in 1757, named after Bern's bears whose legend dates back to 1218, with Berthold V of Zähringen. This square, the center of the old town and an integral part of the UNESCO World Heritage, houses the Bear Fountain from 1852 and a weekly market since the 16th century. Strolling under the Lauben, these continuous 6 km arcades built in the 14th-15th centuries and listed by UNESCO in 1983, you will grasp Bern's intact medieval architectural unity. Your mission ends here, revealing Lucy's secret, the fruit of your exploration of the Bern thematic circuit.
