Trondheim has a history that goes back many centuries. A Viking king named Olav Tryggvason founded the settlement in 997.
Back then, it was called Kaupangen. It served as the capital of Norway until the year 1217. For a long time, it was also the seat of the Catholic Church. The famous Nidaros Cathedral stands in the city today. The city has faced many hard times like big fires. In 1651, a fire destroyed 90% of the buildings.
The city has changed its name many times over the years. Some people used to call it Nidaros. In 1928, people even voted on which name to use.
Most people chose Trondhjem, but the government made some changes later. In 1931, the name was officially changed to Trondheim. This used a medieval Norwegian spelling. The name itself comes from the River Nid. It also means the mouth of that river.

It is a very important part of the Trøndelag region.
Trondheim is a significant city and municipality located in Trøndelag county, Norway.
It sits on the south shore of the Trondheim Fjord. The River Nidelva flows into the fjord at the mouth of the city.
As of January 1, 2026, the municipality has a population of 218,460 people. This makes it the third most populous municipality in Norway. It is also the fourth largest urban area in the country. The city serves as the seat for the County Mayor of Trøndelag. However, the administrative centre for the county is actually located in Steinkjer. This arrangement helps to prevent the county administration from becoming too centralized.
The geography of Trondheim creates a unique environment for its residents. The city has an oceanic or humid continental climate.
Because of its northerly latitude, the sun behaves in extreme ways. During the summer solstice, the sun rises at 03:00 and sets at 23:40. Between May 23 and July 19, the sky stays light enough at night that no artificial lighting is needed outdoors. In contrast, the winter solstice sees the sun rise at 10:01 and set by 14:31. The sun stays very low, reaching an altitude of only slightly more than 3 degrees at midday. While seaside areas often stay above freezing, the microclimate at higher elevations is colder and snowier. The city is mostly sheltered from southwesterly winds but remains exposed to northwesterly winds.
Trondheim's history is deeply tied to its role as a political and religious centre. The settlement was founded in 997 by King Olav Tryggvason.
It was originally named Kaupangen, which means "the marketplace." The name Nidaros was also used, meaning "the outlet of the river Nid." The city served as the capital of Norway throughout the Viking Age until 1217. From 1152 to 1537, it was the seat of the Catholic Archdiocese of Nidaros. Following the introduction of Lutheran Protestantism in 1537, it became the seat of the Lutheran Diocese of Nidaros. This religious importance is marked by the Nidaros Cathedral. People have lived in this region for thousands of years, as shown by ancient rock carvings.
The city's name has undergone several complex changes over the centuries. For a long time, the city was known by the Dano-Norwegian spelling, Trondhjem.
Following the Norwegian language reforms of 1917, many places sought to "Norwegianize" their names. In 1928, a referendum was held to decide between the names Trondhjem and Nidaros. The results showed 17,163 people preferred Trondhjem, while only 1,508 preferred Nidaros. Despite this, the Storting voted to change the cathedral's name to Nidaros in 1929. This caused public outrage and riots in 1930. Finally, on March 6, 1931, the name was formally changed to Trondheim. This used the medieval Norwegian spelling instead of the Danish version.
Trondheim has faced significant physical challenges, particularly from fire and war. Because many buildings were made of wood, the city was ravaged by fires many times. The most devastating fire occurred in 1651 and destroyed 90% of all buildings within the city limits. After the "Horneman Fire" in 1681, General Johan Caspar von Cicignon oversaw a reconstruction. He created broad avenues, such as Munkegata, to limit the spread of future fires. During the Second World War, Nazi Germany occupied the city from April 9, 1940, until May 8, 1945.
The Germans used the city as a major base for submarines, including the construction of the DORA I bunker. They even planned a new city called Nordstern to house 300,000 inhabitants.
Today, Trondheim is a major hub for science, technology, and education.
It is home to the Norwegian University of Science and Technology (NTNU). Other major institutions include the Foundation for Scientific and Industrial Research (SINTEF) and the Geological Survey of Norway (NGU). St. Olavs University Hospital is also headquartered here. The city's growth has been shaped by several municipal mergers. In 1964, Trondheim merged with Byneset, Leinstrand, Strinda, and Tiller. This merger nearly doubled the municipality's population. A further expansion occurred on January 1, 2020, when Klæbu Municipality was merged into Trondheim.
Beyond industry and history, Trondheim is a centre for culture and sport.
The city is home to Rosenborg, which is Norway's most successful football club. It also contains the Granåsen Ski Centre, which has hosted the World Championship in Nordic Skiing. The city's central square, Torvet, serves as a focal point for urban life.
The city's coat of arms reflects its deep history. It features an archbishop and a crowned king to symbolise the historical balance of power between church and state. This unique design has been used since the 13th century and was redesigned by Håkon Thorsen in 1897.
