You are a royal archivist, appointed by Ban Josip Jelačić in mid-19th century Zagreb, tasked with recovering a lost artifact crucial for protecting Croatia's cultural heritage
Dive into the historical heart of Zagreb, where the breath of darkness whispers tales of the first Croatian king and eras of resistance.
« Long live Zagreb! »— Official motto of the city of Zagreb
Your quest begins in Trg kralja Tomislava, Zagreb's main square, named after the first king of Croatia, crowned in 925. Inaugurated in 1895, this vast 40,000 m² expanse houses the equestrian statue of Tomislav, sculpted by Robert Frangeš-Mihanović and erected in 1928, standing 7 meters tall. This location, bordered by the central train station and the Oktogon art pavilion, has been the scene of Croatian national gatherings since independence in 1991, marking its central role in Zagreb's history and Croatian cultural heritage. Your first clues await you under the monarch's gaze.
Nearby, the Oktogon, an octagonal pavilion built in 1897 by Herman Bollé for the Hungarian Millennium Exhibition, stands on Trg kralja Tomislava. With its 16-meter diameter, it was used as a concert hall and gallery from 1898, hosting Croatian art exhibitions as early as 1900. Restored in 2008 after damage from World War II, it testifies to the city's artistic vitality. Your path then leads to Botanički vrt PMF-a, the botanical garden founded in 1889 by the University of Zagreb. Spanning 4.3 hectares, it boasts over 10,000 plant species since 1890, with a central pavilion and 1,000 m² of glasshouses built the same year. Classified as a protected natural monument in Croatia since 1951, this peaceful haven offers a unique setting to decipher Zagreb's secrets.
Your investigation leads you to Muzej Mimara, a Neo-Renaissance palace built in 1892 by architects Klotz. Opened in 1972, this museum displays the collection of 3,750 artworks bequeathed by Ante Topić Mimara in 1971, including pieces by Rembrandt and Velázquez. Its 5 floors offer 2,500 m² of exhibition space, attracting over 300,000 visitors annually before the pandemic. A short walk away, the Hrvatsko narodno kazalište u Zagrebu, the Croatian National Theatre, founded in 1860, reveals itself. Its current building, constructed in 1895 by Ferdinand Fellner and Hermann Helmer, features a Neo-Renaissance facade and a 20-meter pediment. It hosted the premiere of the Croatian opera 'Nikola Šubić Zrinjski' in 1876 and was directed by Ivo Tijardović from 1927 to 1932, a listed monument of Zagreb's cultural life.
The itinerary then takes you into Gornji Grad, the Upper Town, where you enter Prolaz Marije Jurić Zagorke. This narrow passage, opened in 1920 and named after the Croatian writer Marija Jurić Zagorka (1873-1957), directly connects Jelacić and Radić squares. Paved with stone and renovated in 2005 with artistic lighting, this discreet location holds crucial clues. Then, the exploration continues into Tunel Grič, an anti-aircraft tunnel dug in 1943 during World War II, 350 meters long and capable of accommodating 3,700 people. Used as a shelter during Allied bombings in 1944, it has become a contemporary art gallery since 2016, restored in 2017 with LED lighting. The main entrance on Mesničke zaklane square marks a transition between past and present for this historical site.
Finally, your journey concludes in Trg Katarine Zrinske, a square created in 1889 and named in honor of the Croatian noblewoman Katarina Zrinska (1625-1671). Bordered by the Croatian Academy of Sciences and Arts founded in 1866, it testifies to Zagreb's erudition. The statue of Josip Jelačić, erected in 1866, moved in 1947, and reinstalled in 1990, symbolizes perseverance. This location was also a rallying point for Croatian independence demonstrations in 1990. As an archivist, you will have pieced together an essential part of Zagreb's history, connecting the prominent figures and listed monuments that shape the city's identity. You leave with a deep understanding of Zagreb's heritage, from ancient kings to modern writers, and the places where the Croatian nation was born. Vive Zagrebum!
Upon completing your mission in Zagreb, you will have traversed centuries of history, from the reign of King Tomislav to the struggles for independence. Every step, from the grandeur of Trg kralja Tomislava to the hidden corners of Tunel Grič, will have revealed facets of Croatian cultural heritage. You will carry with you not only the secrets of the recovered artifact but also an intimate understanding of Zagreb's monuments and figures like Katarina Zrinska and Marija Jurić Zagorka.
