Trondheim has been a centre of commerce since the Viking Age. Saint Olaf's Way has been an important pilgrimage route. Trondheim has seen the middle ages been one of Norway's three principle cities, along with Bergen and Oslo. The archdiocese of Trondheim covered vast areas of the North Atlantic as it included Norway, parts of Sweden, Iceland, Greenland, Orkneys, Shetland and other parts of the British isles. For two brief years, 1658 to 1660, Trøndelag was part of Sweden.

Trøndelag is separated from East Norway by the Dovre mountains and uplands around Røros. Along the border with Sweden are the Sylan mountains and more modest wilderness further north. Hitra, Frøya and Vikna are major islands and archipelagos on the outer coast, in addition to thousands of smaller islands. There are also islands in the great Trondheimsfjord. Large parts of Trøndelag are related to the long, wide and deep Trondheimsfjord. At well over 100 km it is the third longest in Norway. As a fjord it is partly quite wide almost like a small ocean. Some of Norway's great valleys and rivers terminate at Trondheimsfjord for instance Orkla and Gaula rivers are among Norway's best salmon rivers. There is no clear demarcation between Trøndelag and Møre og Romsdal in the west.

Around the upper part of Namdalen valley there are wide uplands around the border with Nordland. Namsen river at over 200 km is one of Norway's biggest and regarded as Norway's best salmon river only surpassed by Alta river in Finnmark. In and around Namdalen and around Trondheimsfjorden there are wide forests on the modest elevations. Hitra island is the biggest in South Norway. The forests of Trøndelag has Norway's highest density of elg, the Eurasian moose, except Hitra where there is a large number of red deer. The coast and islands around Flatanger and further north has a considerable number of the white tailed eagle (known as havørn or sea eagle in Norway).

Trøndelag has a range of climates. The coastal areas have a typical humid maritime climate where average temperatures in winter are mostly not below 0°C. The outer coast is also exposed to rough wind in Winter. The high plateaus and sheltered valleys of the interior have a continental climate with some of the driest and coldest areas of Norway. Røros has the lowest recorded temperature in South Norway at -50°C. Most of the rain falls near the coast. Autumn and winter are the rainiest seasons. Inner areas have much warmer summers than the coast and islands, temperatures up to 30°C is possible in the inner valleys, while on the coast 25°C is rare.

Trøndelag can be divided into four main sections

• Trondheimsfjorden and adjacent areas including Trondheim, Levanger and valleys ending at the fjord.
• Namdalen valley area including Namsos
• The coast including Hitra island in the south and Vikna archipelago in the north
• The uplands near the watershed including Oppdal and Røros

• 63.59083310.7413895 Frosta. A fertile peninsula in Trondheimsfjorden. Assembly hill (Tinghaugen) at Frosta was the site of the medieval parliament for Trøndelag and adjacent areas. These areas were governed by Frostatingsloven, the law (or law book) of Frosta assembly. This law included the famous phrase at lǫgum skal land várt byggja en eigi at ulǫgum eyða (with law shall our land be built, and not desolated by lawlessness, reproduced in modern Norwegian on the monument there). The law originates from before year 1000 and in oral form perhaps much older, making it one of the oldest in Norway. The law was consolidated in written form around 1100 and is a relatively sophisticated legislation. Several elements of are retained in Norway's modern legislation. Frosta was effectively the capital of Trøndelag until the assembly was moved to Trondheim. (updated May 2020)
• 63.1259.7041676 Orkla Industrimuseum (Orkla mining and industry museum). Copper mining at Løkken began in 1654 and operations ended in 1987 making this one of Norway's oldest businesses.

A private electric railway, Thamshavn Line, was constructed between Løkken and Orkanger port at Thamshavn. Thamshavn Line was in 1908 Norway's first electric railway and is now operated by the museum. (updated May 2020)
• 63.7083019.7220317 Austrått Fort, Austrått, Ørland (Brekstad village). Austrått Fort is a disused coastal artillery at Austrått in Ørland.

The three-gun turret weighs 800 tons and was capable of firing 730-pound shells 38 kilometres (24 mi). It opened as a museum in 1991. Like its sister battery at Sotra near Bergen, a shaft was cut out of the rocks for the huge former Gneisenau battleship gun turret. Along with Fjell fort at Sotra this was one of the largest artilleries along the German "atlantic wall". The fort lis located next to Austrått manor and overlooking the mouth of Trondheimsfjord as well as Ørland Airforce Base. (updated May 2020)
