St. Olav's shrine

The Archdiocese of Nidaros (or Niðaróss) was the metropolitan see covering Norway in the later Middle Ages. The see was the Nidaros Cathedral, in the city of Nidaros (now Trondheim). The archdiocese existed from the middle of the twelfth century until the Protestant Reformation.

Nidaros is a diocese in the Lutheran Church of Norway. It covers Trøndelag county in Central Norway and its cathedral city is Trondheim, which houses the well-known Nidaros Cathedral. Since 10 September 2017, the Bishop of Nidaros is Herborg Finnset. The Bishop Preses, currently Olav Fykse Tveit is also based at the Nidaros Cathedral. The diocese is divided into nine deaneries (prosti). While the Bishop Preses holds episcopal responsibility within the Nidaros domprosti (deanery) in Trondheim, the Bishop of Nidaros holds episcopal authority of the other eight deaneries as well as the language based parish of the Southern Sámi.

Nidaros Cathedral (Norwegian: Nidarosdomen / Nidaros Domkirke) is a Church of Norway cathedral located in the city of Trondheim in Trøndelag county. It is built over the burial site of King Olav II (c. 995–1030, reigned 1015–1028), who became the patron saint of the nation, and is the traditional location for the consecration of new kings of Norway. It was built over a 230-year period, from 1070 to 1300 when it was substantially completed. However additional work, additions and renovations have continued intermittently since then, including a major reconstruction starting in 1869 and completed in 2001. In 1152, the church was designated as the cathedral for the Catholic Archdiocese of Nidaros. In 1537, during the Protestant Reformation, it became part of the newly established state Church of Norway. It is the northernmost medieval cathedral in the world.The cathedral is the main church for the Nidaros og Vår Frue parish, the seat of the Nidaros domprosti (arch-deanery), and the seat of the Bishop of the Diocese of Nidaros. The Preses of the Church of Norway is also based at this cathedral. The church seats about 1,850 people.

The Nidaros Cathedral West Front (Nidarosdomens Vestfront), which includes multiple sculptures, was the final portion of the Nidaros Cathedral in Trondheim, Norway that was restored. Nidaros Cathedral is the world's northernmost medieval cathedral and Norway's national sanctuary. The West Front is the cathedral's main facade and one of the most beautiful and ornate portions of the church. The restoration of the West Front took from 1905 to 1983 and was worked on by a large number of sculptors. In 1869, the Nidaros Cathedral Restoration Workshop was founded with the purpose of restoring the Cathedral, and celebrated a 150 years Anniversary in 2019. A picture of the West Front from 1661 shows extensive deterioration, with only the bottom sections left standing. Only five statues from the Middle Ages have survived. The restoration of the West Front took from 1905 to 1983 and was worked on by a large number of sculptors. The largest church bell in Norway hangs in the West Front's north tower. Installed in 1964, it weighs 2,400 kg, and people say that it can be heard in Melhus, all of 30 km away, when the wind is in the right direction. The church has three bells. The 'Great Bell' is the oldest and was cast in Hoorn in the Netherlands in 1751. This part of the church is also the most recent of the original cathedral constructions; archbishop Sigurd Eindrideson laid the cornerstone for the west front in 1248. The construction was not yet complete when the church was burnt in 1328. The original design for the west face is not known, but one can assume that it was never built to those original plans; it is reasonable to assume that a screen front similar to that used elsewhere was planned on the west. Screen fronts were often rectangular and served as a cover to conceal the rest of the church. English cathedrals from the same period, among others Lincoln Cathedral, Wells Cathedral and Salisbury Cathedral, had similar fronts. The west front had three entrances and is flanked by two smaller towers on each side of the façade.

Nordenfjells or Nordafjells ("North of the Mountains") is currently a name for the area of Norway north of mountain range of Dovrefjell. The term is largely used when referring collectively to Central Norway and Northern Norway. Until around 1800 the name also included all of Western Norway. The largest city is Trondheim, with the Trondheim Region having a population of 260,000. Historically, an administrative division of Norway in Sønnenfjells and Nordenfjells has been used from the Middle Ages until around 1800. The border between the two regions was a range from Åna-Sira or Lindesnes, northwards along Langfjella and Dovrefjell. What is today known as Western Norway (Vestlandet) was defined as part of Nordenfjells. The notion of Western Norway was introduced in the 1800s. Erik Pontoppidan was one of the first to use the notion of vestenfields (west of the mountains) as distinct part of Nordenfjells. Pontoppidan observed the notable differences in climate between east and west. Later William Thrane wrote that western Norway included most of Christiansand dicose (Agder, Rogaland and western Telemark). Hans Strøm used the old distinction where «nordenfjells» included western Norway. Christopher Hansteen travelled across Hardangervidda in 1821 and observed that his compassed apparently had a 90° deviation: People in Eastern Norway said they traveled "north" to Hardanger and people from the west were known as "nordmenn". Christian Magnus Falsen in 1822 used Vestlandet about Agder and Jæren. Ivar Aasen's dictionary from 1850 og 1873 use vestlending og Vestlandet as these names are used today.Norge (Norway) and nordmenn in the Middle Ages were names for the coastal areas from Agder to Hålogaland, and the people there. Ohthere of Hålogaland used these names in his report to King Alfred in year 890. When the kingdom expanded the old labels nordmenn and nordenfjells were still used about the coastal/fjord areas in the west while the eastern areas, Østlandet, were inhabited by austmenn (eastern men).

The Trondheim Art Museum has two venues, TKM Bispegata (Bispegata 7 b) situated near the Nidaros Cathedral and TKM Gråmølna at Nedre Elvehavn. The main building in Bispegata 7 b was built in 1930 according to plans by architect Peter Daniel Hofflund. The Trondheim Art Museum was established in 1997, as a means to maintain the museum collection. The building has two floors with rooms of varied sizes and light. The building was refurbished in 2012, when artificial lights were installed to provide more stable temperature and lighting. Much of the interior was restored to its original state from 1930.
