# Sirdal

Sirdal is a municipality in Agder county, Norway. It is located in the northwestern part of the traditional district of Lister. The administrative centre of the municipality is the village of Tonstad. Other villages in Sirdal include Bjørnestad, Haughom, Kvæven, Lunde, and Tjørhom.
The 1,554-square-kilometre (600 sq mi) municipality is the 52nd largest by area out of the 356 municipalities in Norway. Sirdal is the 290th most populous municipality in Norway with a population of 1,837. The municipality's population density is 1.3 inhabitants per square kilometre (3.4/sq mi) and its population has inmcreased by 0.3% over the previous 10-year period.

## General information

The old parish of Sirdal was first established as a municipality in 1849 when it was separated from the large municipality of Bakke. Initially, Sirdal had 1,804 residents. On 1 January 1903, a small area of Sirdal (population: 63) was transferred to the neighboring municipality of Fjotland. On 1 January 1905, the municipality of Sirdal was dissolved and its territories were divided into two new municipalities: Tonstad (population: 828) and Øvre Sirdal (population: 753). These large, sparsely populated municipalities merged along with the Øksendal area of Bakke municipality to recreate the municipality of Sirdal on 1 January 1960. This time, Sirdal started out with a population of 1,426. On 1 January 1987, the Virak and Espetveit areas of northern Flekkefjord (population: 41) were transferred to Sirdal municipality.

### Name

The municipality (originally the parish) is named after the Sirdalen valley (Old Norse: Sírudalr) since the valley runs through the municipality. The first element is the genitive case of the river name Síra (now the Sira river). The river name has an unknown meaning, but it could be something like "strong stream". The last element is dalr which means "valley" or "dale".

### Coat of arms

The coat of arms was granted on 17 January 1986. The official blazon is "Vert, three ptarmigans volant argent" (Norwegian: I grønt tre oppflygande sølv ryper, 2 - 1). This means the arms have a green field (background) and the charge is a willow ptarmigan (Lagopus lagopus). The ptarmigan has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. The green color in the field and the ptarmigans were chosen as a symbol for the hills and moorland which make up the largest part of the municipality. The willow ptarmigan is a typical bird for the area. The arms were designed by Stein Davidsen. The municipal flag has the same design as the coat of arms.

### Churches

The Church of Norway has one parish (sokn) within the municipality of Sirdal. It is part of the Lister og Mandal prosti (deanery) in the Diocese of Agder og Telemark.

## Geography

Sirdal municipality includes the westernmost valley in Agder county, bordering Rogaland county to the west. To the south, it borders on the municipality of Flekkefjord and to the east is Kvinesdal. Sirdal is the largest municipality by area in Agder. Lakes in the region include Gravatnet, Kulivatnet, Kvifjorden, Øyarvatnet, Rosskreppfjorden, Sirdalsvatnet, and Valevatn. The mountain Urddalsknuten lies at the northern end of the municipality.
In 1990, the mountain road opened between the Sirdalen valley and the Setesdal valley over the Suleskard mountain pass. It connected Sirdal to Brokke in the neighboring municipality of Valle to the east. It shortened the distance from Oslo to Stavanger by 110 kilometres (68 mi) in the summer, and the road passes through barren, glacier-scoured highland. As it passes by the Rosskreppfjorden, it ascends to over 1,000 metres (3,300 ft) above sea level.

## Economy

The main source of income for Sirdal is the Sira-Kvina Power Company which gets its power from the big Sira and Kvina rivers. The waterfalls on the river Sira are utilized in four power stations owned by Sira-Kvina power company. The company also owns three power stations in the Kvina river system, hence the company's name. Total annual production is 6,000 gigawatt-hours (22,000 TJ), total installation is 1,760 megawatts (2,360,000 hp). The largest power station, Tonstad Hydroelectric Power Station, was inaugurated in 1968, with two units, each producing 160 megawatts (210,000 hp). The power station has now 4 units, each 160 MW, and one unit at 320 megawatts (430,000 hp), giving a total output of 960 megawatts (1,290,000 hp). Total annual production in this station is approximately 4,000 gigawatt-hours (14,000 TJ), which makes Tonstad the largest power station in Norway in terms of production. Sira-Kvina power company applied in 2007 for concession to expand the power station with two new units (reversible turbines), each containing 480 megawatts (640,000 hp), and the concession is pending.
The number of wind turbines is 51; in 2024, a political process for more wind turbines, was ended by a municipal council vote.
Tourism is also an important source of income for the Sirdal economy, taking advantage of the extensive mountains, mountainous plateaus, lakes, and great views. There are multiple alpine resorts and hotels in the valley, as well as cottages and camping spots. Winter activities include six ski resorts for winter enjoyment. Downhill ski areas include Tjørhomfjellet, Bjørnestad Ski Centre, Ålsheia Ski Centre, Fidjeland Ski Centre, and Ådneram Ski lift. Cross-country skiers can enjoy dozens of trails over spectacular terrain. Summer activities include hiking, horseback riding, and river rafting.

## History

From the oldest times the Sirdalen valley was divided by the river Sira with Rogaland county controlling the west side and Agder county controlling the east side. The two sides of the valley, however, was established as one single parish in Christian times, even though it crossed county lines, something that was not very common in Norway.
In 1837, it was decided that every parish should be a municipality, but no municipality should belong to more than one county (see formannskapsdistrikt law). Sirdal parish was therefore first divided in two municipalities. This was a bad decision because they had very few inhabitants separately. A new solution was found in 1839 when the two municipalities were re-joined, and the county border was moved so that all of Sirdalen was in Vest-Agder county.
At Kvæven, in northern Sirdal one finds the Sirdal Mountain Museum. This museum has a collection of old Sirdal buildings. Former lifestyles are visible in the farmhouse, a schoolhouse, stable, blacksmith's shop, barn, and mountain farm cottage as well as original equipment.
