Klæbu is a former municipality in Trøndelag county, Norway. It existed from 1838 until its dissolution in 2020 when it was incorporated into the neighboring Trondheim Municipality. It was located in the southern part of the Trondheim Region, about 20 kilometres (12 mi) south of the city of Trondheim. The administrative center was the village of Klæbu. The other major village in Klæbu municipality was Tanem.

Even though agriculture has traditionally been the main industry for Klæbu, the municipality most recently functioned more as a commuter town of Trondheim, where many of Klæbu's inhabitants work or attend school.

At the time of its dissolution in 2020, the 186-square-kilometre (72 sq mi) municipality was the 337th largest by area out of the 422 municipalities in Norway. Klæbu was the 171st most populous municipality in Norway with a population of 6,094. The municipality's population density was 34.8 inhabitants per square kilometre (90/sq mi) and its population had increased by 9.6% since 2010.

General information

The municipality of Klæbu was established on 1 January 1838 (see formannskapsdistrikt). On 1 January 1899, the small northwestern part of Klæbu (population: 533) was separated from Klæbu to form the new municipality of Tiller.

On 1 January 2018, the municipality switched from the old Sør-Trøndelag county to the new Trøndelag county.

On 1 January 2020, the municipality of Klæbu merged with the municipality of Trondheim to the north.

Name

The municipality (originally the parish) is named after the old Klæbu farm (Old Norse: Kleppabú) since the first Klæbu Church was built there. The first element is the plural genitive case of kleppr which means "rocky hill". The last element is bú which means "rural district". The district/parish has a lot of small rocky hills.

Coat of arms

The coat of arms was granted on 8 July 1983 and it was in use until 1 January 2020 when the municipality was dissolved. The official blazon is "Argent, flaunches azure" (Norwegian: I sølv to buede blå flanker). This means the arms have a field (background) that has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. Each side of the arms have blue flaunches. The arms symbolize the Trangfossen waterfall in the Nidelva river, which is now the deepest canyon in Norway measuring 56 metres (184 ft). The river has been of great importance for the local development, for agriculture and hydroelectricity generation, hence the use of the waterfall as a typical symbol for the municipality. The waterfall is no longer visible as that part of the river became part of Bjørsjøen lake after the building of the dam at Hyttfossen. The arms were designed by Einar H. Skjervold.

Churches

The Church of Norway had one parish (sokn) within the municipality of Klæbu. It is part of the Heimdal prosti (deanery) in the Diocese of Nidaros.
