The story that haunts this land
Your investigation begins at Linz's Hauptplatz, the main square reshaped in 1230 by Frederick II, Holy Roman Emperor. This 12,000 m² esplanade, lined with 17th-18th century baroque buildings, was the scene of dark events. In 1943, a 20 m deep trench was dug here for anti-aircraft defense, forced labor by deportees. You examine the Trinity Fountain, built between 1740 and 1742, a UNESCO baroque heritage monument that silently witnessed these radical transformations of the city of Linz's heart.
A short walk away, the Altes Rathaus, the old town hall, stands. Built in 1320-1326 and extended in 1513 by Emperor Maximilian I, this late Gothic building with Renaissance additions features a 45 m long facade. In 1938, Hitler participated in a military parade here during the Anschluss, an event that marked the city. The 65 m high watchtower, an emblem of Hauptplatz, offers a unique vantage point over this birthplace of Adolf Hitler and its historical heritage.
The route then takes you to Landstraße, a historic road connecting Hauptplatz to Linzer Schloss since the 13th century. It was at No. 9 on this 6-8 m wide cobbled street, typical of old Linz, that Adolf Hitler was born on April 20, 1889. The birthplace, razed in 1945 by Allied authorities, is a central point of your investigation into the erased secrets of Linz. This artery is an Austrian historical monument that holds a sensitive part of Upper Austria's history.
Continue towards Linzer Schloss, a castle built around 1280 by Frederick II and a Habsburg residence. Now the Museum of Upper Austria, this 5,500 m² fortress was also a place where Hitler stayed during his official visits between 1938 and 1942. The main towers, 30 m high, dominate the city, offering a panorama of the Danube and Linz's rich past. This site allows you to understand Hitler's attachment to this Upper Austrian city, which he considered his childhood home.
Your archivist mission concludes with a reflection on Linz's heritage. From Hauptplatz to Landstraße, passing through Altes Rathaus and Linzer Schloss, you have traced an itinerary that goes beyond a simple tourist visit. You have explored the monuments of Upper Austria and the key sites in Linz's history, discovering how architecture and urban planning bore witness to the turmoil of the 20th century. This thematic circuit through historic old Linz leaves you with a deeper understanding of the events that shaped this city, far beyond typical tourist anecdotes.
