Our journey through time begins with Trondheim's most important monument - Nidaros Cathedral (Nidarosdomen). This majestic Gothic temple, which is the largest medieval cathedral in Scandinavia, is the historical heart of the city and the resting place of St. Olaf, the patron saint of Norway. The cathedral impresses not only with its monumental architecture, but also with its rich history dating back to the 11th century. Visitors can admire intriguing architectural details, including the famous West Rose, an impressive stained glass window on the western facade. Nidaros Cathedral has received an impressive rating of 4.7 in reviews by tourists, who highlight its 'incredible impression' and 'beauty.' It is worth remembering that an entrance ticket costs about NOK 120 for an adult (as of 2023).

Not far from the cathedral is another historical gem - the Archbishop's Palace (Archbishop's Palace, Trondheim). This complex of buildings, one of the oldest in Scandinavia, was once the seat of the powerful archbishops of Nidaros. Today, it houses several fascinating museums, including the Crown Insignia Museum, where Norwegian royal regalia can be admired. The Archbishop's Palace, with a rating of 4.4, offers an unusual combination of history, archaeology and art. Visitors especially praise the 'fantastic free exhibition' that combines modern technology with traditional exhibits.

Moving on to the next point of our trip, Gamle Bybro, or Old City Bridge, should not be missed. This distinctive red bridge, which connects the old town with the Bakklandet district, is not only an important transportation element, but also one of the most picturesque places in Trondheim. Built in the 17th century, the bridge offers beautiful views of the colorful wooden houses on the Nidelva River. With a rating of 4.7, Gamle Bybro is a favorite of tourists and locals alike, ideal for walking and photography. In the words of one reviewer: 'A beautiful place with wonderful views. Highly recommended.

These three sites - Nidaros Cathedral, the Archbishop's Palace and the Old City Bridge - form a triangle of Trondheim's historic heart, offering an unforgettable experience for lovers of history, architecture and picturesque views. Each of these sites tells a different part of the city's rich history, allowing visitors to immerse themselves in the atmosphere of medieval Norway.

Continuing our journey through time in Trondheim, we move on to less obvious but equally fascinating sites that reveal further layers of the history of this remarkable city.

We begin with an unusual site - Kirken under gaten, or Church under the Street. Hidden beneath the streets of modern Trondheim, this fascinating archaeological museum showcases the remains of the medieval St. Clement's Church.

This venue perfectly demonstrates how modern technology can bring history to life, making it accessible and fascinating for all generations.

The next point on our tour is the Jewish Center in Trondheim. This place, with a rating of 4.6, tells the story of the Jewish community in Norway, focusing particularly on the dramatic events of World War II. The museum is housed in an 1864 building that was originally a train station, and since 1925 has served as the northernmost synagogue in Europe. Visitors praise the interesting exhibitions and the opportunity to learn about a lesser-known part of Norwegian history.

We can't leave out the Armory (Rustkammeret), a fascinating museum dedicated to Norway's military history. With a rating of 4.6, this museum offers an impressive collection of weapons, uniforms and military equipment from Viking times to the present. Visitors especially appreciate the opportunity to interact with the exhibits: 'You can try on parts of a soldier's closet, including a Viking outfit.' This is an ideal place for families, where history becomes tangible and interactive.

The last item in this section is Riksregaliene, which is a museum of Norwegian royal regalia. Located in the vault of the Archbishop's Palace, the museum displays the crowns, scepters and other insignia of power of the Norwegian royal family. With a rating of 4.2, the site, though small, offers a remarkable experience. As one visitor notes: 'A magnificent collection of royal crowns and regalia. True works of art. It's worth remembering that no photos are allowed in the museum for security reasons, which only adds to the mystery and exclusivity of the place.

Each of the sites offers a unique look at different aspects of Trondheim and Norwegian history. From medieval relics hidden underground, to the tragic history of the 20th century, to symbols of royal power, these sites create a fascinating mosaic of stories about the city's and country's past. They are less well known than the main tourist attractions, but they are often where the most fascinating stories and unexpected discoveries lie.

In the final part of our journey through Trondheim's historical treasures, we will focus on sites that offer a broader perspective on the history and culture of this fascinating city.

Let's start with the Sverresborg Trøndelag Folk Museum, a remarkable open-air museum located on the outskirts of the city. This place, with an impressive 4.6 rating, is a real gem for lovers of history and folk culture. The museum, located around the ruins of a medieval castle, offers a fascinating journey through centuries of Norwegian history. Here, visitors can see recreated buildings from different eras, from traditional rural huts to urban craft workshops. As one reviewer notes: 'The museum is located a bit out of the way, although you can take a bus to the entrance itself. Ticket prices are affordable. The open-air museum contains objects from Trøndelag and is divided into urban and rural sections.' It's an ideal place for families, where history comes to life and children can learn about the daily life of old Norwegians in an interactive way.

The next point on our map is Kristiansten Fortress. This 17th-century fortress, towering over the city, offers not only a fascinating lesson in military history, but also beautiful views of Trondheim and the surrounding fjords. With a rating of 4.5, the fortress is a favorite walking destination for tourists and locals alike. Importantly, admission to the fortress is free, making it an excellent option for frugal travelers. As one visitor notes: 'Towering above Trondheim, the 17th-century fortress provides an excellent vantage point overlooking the city and, in good weather, even the surrounding fjords.'

At the end of our trip, it is worth mentioning a place that, although not a typical monument, is a fascinating combination of history and modernity - Rockheim. It's an interactive museum dedicated to the history of Norwegian popular music, with a special focus on rock. With a rating of 4.4, Rockheim offers an extraordinary multimedia experience that takes visitors through the decades of the Norwegian music scene. In the words of one reviewer: 'Probably the best museum I've had the opportunity to be in. Super interactive and modern.' This place shows that history doesn't end in the distant past, but is a continuous process that continues today.

When comparing these places, it is worth noting their diversity and complementarity. Sverresborg offers a broad panorama of daily life over the centuries, Kristiansten Fortress focuses on military and strategic aspects, and Rockheim shows how history is intertwined with the present. Each of these sites has its own unique advantages: Sverresborg is ideal for families with children, offering interactive experiences and beautiful surroundings. Kristiansten Fortress is a great option for frugal travelers and lovers of beautiful views. Rockheim, on the other hand, will be an ideal choice for younger tourists and music fans.
