The story that haunts this land
Your quest for Zurich's Forgotten Testament begins on Paradeplatz, a public square created in 1850 from the demolition of medieval ramparts. This financial crossroads, named after 19th-century military parades, is bordered by the neoclassical headquarters of Credit Suisse (now UBS), built in 1873. On this 12,000 m² surface, surrounded by historic cafés like Confiserie Sprüngli, founded in 1836, you collect the first fragments of a banking conspiracy that could shake Swiss heritage.
Continue towards the SIX Swiss Exchange at 82 Selnaustrasse, near Paradeplatz. Founded in 1850 as Börse Zürich, this institution is the beating heart of the Swiss stock market. The modern building from 2007, designed by architect Meinrad Kahr, houses up to 1,000 traders and manages an average daily transaction volume of 7.5 billion CHF in 2023. Here, digital clues and coded messages await you, hidden in data flows and contemporary architectures, revealing the complexity of Zurich's financial system.
The path then leads you along the Schanzengraben, a bastioned rampart moat built in 1642 to fortify Zurich against the Swedes. This 1.2 km canal, transformed into a public promenade in 1830, retains nine historic bastions and is lined with plane trees planted around 1850. It's a relaxing spot with views of Lake Zurich, but for you, it holds discreet clues, messages left by period informants who used this quiet path for their secret meetings.
Approaching the Zunfthaus zur Meisen on Limmatquai, you discover a millers' guild house, built in 1705-1712 in Baroque style by Johann Caspar Glenck. Classified as a historic monument in 1947, this 1,200 m² building even served as the headquarters of the Swiss National Bank from 1905 to 1920. The Baroque ornaments and archives of this Altstadt Zurich residence could contain crucial information about the financial transactions that marked the history of the Confederation, a true Swiss historic monument. Cross the Münsterbrücke, a bridge over the Limmat built in 1835-1839, connecting the Grossmünster and Fraumünster churches, to reach the next stage of your investigation.
Your journey through Zurich's heritage finally leads you to the Schweizerische Nationalbank, with its main headquarters at Börsenstrasse 15 since 1923. This Swiss central bank, founded on January 16, 1907, occupies a neoclassical building from 1921 by Hermann Bilz, housing 1,040 tons of gold reserves in 2023. By exploring this site, you unravel the last pieces of the puzzle, understanding the scope of Zurich's financial history. You will have traversed the heart of the city, from Lindenhof, the site of a Roman castellum from 15 BC, to the medieval district of Schipfe, with its 42 listed buildings. This thematic circuit will have offered you an interactive tour of the Financial District Zurich and its past, a true GPS treasure hunt in the heart of Switzerland.
