The story that haunts this land

Your Zurich investigation begins at the Helmhaus, a building constructed in 1800 as the weavers' guild house. Its classical Zurich facade, typical of the 19th century with its mullioned windows, conceals the first clues. From there, you cross the Limmat to reach the Lindenhof, a hill fortified since Roman times. This site, which housed Turicum in the 1st-2nd centuries and a fortress destroyed in 1798, offers a panoramic platform over the Old Town and the Limmat. It is here, on this medieval gathering place, that you will decipher the first secret communications.

Descending from the Lindenhof, you reach the Predigerkirche, a church erected in 1231 for the Dominican order. Its interior, simplified during the Protestant Reformation in the 16th century, and its historic pulpit recall the influence of the Zurich reformers. Continue then to the Grossmünster, the cathedral founded in 1100 whose twin towers, completed in 1782, rise 115 meters high. This monument, the seat of the Protestant Reformation with Ulrich Zwingli between 1519 and 1531, holds symbols that Lenin could have manipulated for his own revolutionary ends.

Your route then takes you to Niederdorfstrasse, a medieval cobbled alley from the 13th century, the bohemian heart of Zurich. It was in this district that Vladimir Lenin resided in 1916, during his Swiss exile. The historic cafes and small shops retain the atmosphere of this Old Town, conducive to discreet meetings. You will then discover Spiegelgasse 14, the 17th-century building where Lenin rented an apartment from February 1916 to April 1917. A commemorative plaque in German and Russian still marks this key location in revolutionary history.

The itinerary continues towards the Kunsthaus Zürich, an art museum founded in 1910 in an Art Nouveau style building. Although Lenin did not frequent this place, its collections covering medieval, modern, and contemporary art testify to the cultural effervescence of Zurich, an intellectual setting where revolutionary ideas could germinate. The museum, located approximately 1.5 km from the starting point, offers a perspective on Zurich society of the time, between tradition and avant-garde.

Your investigation concludes at Bürkliplatz, a public square laid out in 1892 at the confluence of the Limmat and Lake Zurich. This popular gathering space and historical transit point, with its access to public transport and panoramic views of the historic districts, is the ideal location for a final exfiltration. As an agent, you will have unraveled the threads of the Red Conspiracy, tracing Lenin's footsteps through Zurich's historical heritage, from the UNESCO Old Town to the streets of the Niederdorf district, and measured the impact of the Protestant Reformation on revolutionary thought.
