What to see in Heidelberg, Germany

Heidelberg is a charming small city located along the Neckar River in the German state of Baden-Württemberg. It is often referred to as Germany’s most romantic city. Although it has suffered destruction multiple times throughout its long history, its ruins, architecture, and atmosphere continue to inspire artists and enchant both visitors and residents.

Personal Experience in Heidelberg

I have been living in Heidelberg for two months. While that is far from enough time to fully understand the city, I have already found places I love and others I strongly recommend to anyone visiting this lively and beautiful destination.

Heidelberg Castle

A visit to Heidelberg would feel incomplete without seeing its castle. It is often said that skipping the castle is like going to Rome without seeing its most famous landmark. Although commonly called a castle, it is actually a baroque ruin and one of the city’s defining symbols.

Reaching it involves a steep climb, but visitors can also take the Bergbahn funicular, which makes the journey easier and offers impressive views over the city—especially at sunset. The site is ideal for those interested in history, as it once served as the residence of the Prince Electors and was connected to important figures of the Holy Roman Empire, including Frederick V.

Admission typically includes the funicular ride, access to the castle courtyard, the German Pharmacy Museum, and the cellar area where the famous Heidelberg Tun, a massive wine barrel known worldwide, is displayed.

The Old Town (Altstadt)

The Altstadt is not easily summarized in a single description. To truly understand Heidelberg, walking through its old town is essential. A free walking tour is highly recommended, as guides provide historical context and interesting stories that are easy to miss otherwise, such as the unusual tale behind the pretzel symbol found on one of the city’s church walls.

A good starting point is Bismarckplatz, where public transport converges. From there, Hauptstraße stretches through the heart of the old town, connecting key locations such as Universitätsplatz, Marktplatz, and Karlstor.

In Marktplatz, you will find the Heiliggeistkirche, a Gothic church historically linked to religious divisions between Catholics and Protestants. It also played a role in the founding of the University of Heidelberg and the Palatine Library. The Alte Brücke, commissioned by Karl Theodor, features statues including the ruler himself, the goddess Minerva, and the famous Brückenaffe monkey figure. Tradition says touching the statue brings fortune, prosperity, or even fertility.

Philosopher’s Walk

Another well-known attraction is the Philosophenweg, or Philosopher’s Walk. Although I have not personally completed it, it is highly recommended, especially on clear days. The path is somewhat steep, but the reward is a panoramic view of Heidelberg, the river, and the castle—scenery often featured on postcards.

Final Impression

Heidelberg may be small compared to major cities, but it is rich in history, charm, and memorable sights. Anyone who visits is likely to understand why poets, artists, and travelers have long been drawn to it—and perhaps even leave a piece of their heart behind.
