Zagreb — Edison's Plot Against Tesla
You are a young Croatian engineer, arriving at Glavni kolodvor Zagreb in 1892, the central station inaugurated by Emperor Franz Joseph I.
Your mission: thwart Edison's electrical
Dive into 1892 Zagreb, an electric city where Thomas Edison's shadow threatens Nikola Tesla's revolutionary innovations.
The story that haunts this land
Your investigation begins at Glavni kolodvor Zagreb, the central station built in 1892 in a Neo-Renaissance style. This 170-meter-long building was a key passage point for Nikola Tesla in 1875, as he arrived for his studies. The station, restored in 2007 to preserve its original mosaics and stained glass, is the first clue to the tension hanging over Croatia's cultural heritage. Here, you must find the first encrypted message left by a Tesla ally before Edison's agents discover it among the 20,000 daily passengers.
Next, your journey leads you to the Hrvatski državni arhiv, founded in 1850 and housed in the former Mišićev Royal Palace, built in 1764. This 3-story baroque building holds over 30 linear kilometers of historical documents, including Nikola Tesla's archives related to his Croatian patents and family correspondences. Open to the public since 1948, this edifice is crucial for deciphering Edison's intentions. You search for clues among the parchments and registers, hoping to find proof of the plot before it is destroyed or falsified.
The tension mounts as you arrive at Trg kralja Tomislava, a square created in 1898 and named after the first Croatian king, Tomislav, crowned around 925. This 40,000 m² esplanade, adorned with a fountain built in 1928, was the scene of historical gatherings, such as the proclamation of the Kingdom of Serbs, Croats, and Slovenes in 1918. Tomislav's 17m high equestrian statue, erected in 1940, dominates the square. It is here, under the gaze of the bronze and granite king, that you must meet a secret contact who will reveal a crucial part of Edison's plot, a secret buried in the history of Zagreb.
Your quest then takes you to Sveučilište u Zagrebu, Croatia's oldest university, founded in 1669 by the Jesuits. Nikola Tesla studied physics and mathematics here from 1875 to 1877. The central buildings, constructed in 1889 in a Neo-Renaissance style, house a university library founded in 1777 with 2 million volumes. Within these knowledge-filled walls, you must decipher Tesla's lecture notes to anticipate Edison's next move. This visit to the University of Zagreb is a deep dive into the genius's mind.
Finally, your journey concludes at Trg bana Josipa Jelačića, Zagreb's central square since 1848, named after Ban of Croatia Josip Jelačić (1848-1859). His equestrian statue, erected in 1866, dominates a 20,000 m² area. Surrounded by Viennese Secession buildings (1900-1910), this square was the center of the 1848 revolutions and a place where Tesla delivered speeches during his visits. It is here that you unmask the plot, saving Tesla's reputation and securing the future of his inventions. This exploration of the historic center of Zagreb makes you a key player in the city's history, forever marking the Zagreb Tesla Route.
