Ski is a town in Nordre Follo municipality in Viken. The
settlement had a total of 20,144 inhabitants as of 1 January 2020
and extends into Ås municipality. Ski is the administration center
for Nordre Follo municipality. In 2004, the municipal council in Ski
chose to give the town city status.
The eastern and western
lines of the Østfold line meet at Ski, and the place therefore
became from 1878 a communication center for parts of eastern Viken.
Ski is said to be a typical station town. A typical feature of the
town is its extensive use of brick, which is repeated in the largest
apartment buildings as well as Ski Storsenter and the town hall. In
the village are among other things Ski station, a hospital and Ski
stadium. There is an industrial area on the outskirts of the town.
Ski Storsenter was expanded in 2003 with a large number of shops, a
large cinema with eight halls, an expanded library and Thon Hotell,
and is the first so-called multi-center in Norway. On 15 October
2008, the center was again expanded with access to a new floor.
The name "Ski" comes from the old form Skeidi which is derived
from the word skeid. Skeid means a place where you hold races . The three horse heads in the municipal coat of arms of the
old Ski municipality symbolize this origin.
Etymology
The name "Ski" (pronounced roughly "shee" in Norwegian)
originates from a medieval farm called Skeidi (Old Norse Skeiði, a
variant of skeið). This term refers to a "running track" or "course,"
specifically for horse racing or similar competitions, suggesting a
historical horse-racing track existed at the site. It has no connection
to the sport of skiing (despite the coincidental English word), which
derives from the same Old Norse root skíð meaning a split piece of wood
or plank. The municipality adopted the name from the central farm/town
area.
The coat of arms (granted 1986, based on a 1979 design) depicts
three silver horse heads arranged in a triskelion on a blue field,
directly referencing this horse-racing etymology.
Prehistoric and
Ancient History
Archaeological evidence shows human settlement in the
Ski and nearby Ås areas dating back approximately 11,000 years, shortly
after the last Ice Age. The Stunner site represents the oldest known
settlement traces in Akershus county, linked to the Fosna culture (a
Mesolithic hunter-gatherer tradition). Stone Age tools continue to
surface during plowing, with over 300 registered ancient artifacts
documented in Ski alone. Iron Age burial mounds are present, including
the largest in the Follo district at Kråkstad Church. Two historical
"royal roads" also traverse the area, indicating long-standing
connectivity and cultural landscapes shaped by early agriculture.
Medieval Period
During the Middle Ages, the areas of Ski and
Kråkstad formed separate church parishes, each with stone churches
constructed around 1150 (Romanesque style). The Ski medieval church,
seating about 200, underwent major renovations in 1860 and 1934 and
remains a landmark. Burial mounds and other remains from the Iron
Age/Viking period complement these structures. The region was rural,
centered on farming, with the Skeidi farm as a notable site.
19th
and Early 20th Century Development
The area remained predominantly
rural and agricultural into the 19th century, with Kråkstad serving as
the political and administrative center. A pivotal turning point came
with the opening of the Østfold Line (Østfoldbanen) railway in 1879,
which established Ski as a station town. This infrastructure spurred
growth, transforming Ski into a commercial and trading hub by attracting
businesses, logistics, and residents. Commuting to Oslo increased over
decades due to housing pressures in the capital, immigration, and strong
local birth rates.
Municipal and Administrative Changes
Originally part of Kråkstad municipality (established 1837).
On July
1, 1931, Kråkstad was divided: the northern portion (centered on Ski)
became Ski Municipality, while the south retained Kråkstad.
By the
1960s, Ski had grown significantly in population and economic
importance. On January 1, 1964, Kråkstad was fully merged into Ski
Municipality.
On January 1, 2020, as part of Norway's municipal
reform, Ski merged with neighboring Oppegård to form Nordre Follo
Municipality (population ~59,000 at merger), with Ski as the de facto
administrative center.
Notable Events
A unique historical
event occurred on January 26, 1848, when the first meteorite discovered
in Norway fell over Ski (the "Ski meteorite").
Modern Era,
Economy, and Culture
Traditionally agricultural (farmland and forests
dominate the landscape of rolling hills and moraine deposits), Ski
evolved into a mixed economy emphasizing commerce, services, logistics,
and headquarters for regional companies, driven by its transport
advantages. Ski Storsenter is one of Norway's largest shopping centers.
Population density is higher in western and central areas (e.g., Langhus
suburb connecting toward Oslo, Kråkstad village, Siggerud). The demonym
is "skiung."
Culturally, amateur sports clubs thrive; Follo FK
(football/soccer team based in Ski) has competed in Norway's top
divisions and reached national cup finals. Twin/sister cities include
Gladsaxe (Denmark), Viimsi Parish (Estonia), and Solna (Sweden). Local
history is documented in works like Terje Schou's Ski og Kråkstad inntil
omkring 1500 and Martin Østlid's bygdebok on Kråkstad.
Ski is a town and former municipality now part of Nordre Follo
Municipality in Akershus (Viken) county, in the Follo district of
southeastern Norway, approximately 20–30 km south of central Oslo.
It
lies inland, separated from the Oslofjord by neighboring municipalities
like Oppegård (now part of Nordre Follo) and Ås. The town serves as the
de facto administrative and commercial center of Nordre Follo (formed in
2020 by merging Ski and Oppegård) and the broader Follo region.
Approximate coordinates are around 59°45'N, 10°52'E. Major transport
corridors—the E6 and E18 highways and the main Oslo–Stockholm/Gothenburg
railway—pass through or near Ski, making it a key hub despite its
rural-agricultural roots.
Topography and Terrain
The landscape
features gently rolling hills rather than dramatic mountains or fjords
typical of western or northern Norway. Elevations in the Ski area range
from a minimum of about 16 ft (5 m) to a maximum of around 659 ft (201
m), with an average elevation of roughly 410 ft (125 m); the broader
Nordre Follo area averages around 142 m (466 ft). The terrain is
generally hilly but accessible, shaped by glacial activity.
Geologically, the area rests on ancient Precambrian bedrock foundations
common to much of the Oslo region, overlain by glacial moraines
(deposits of till and sediment) from the last Ice Age that extend
east-west through Follo. These moraines contribute to fertile soils and
undulating topography. The former Ski municipality covered about 165.5
km² (161.5 km² land), of which roughly 61.5% (102 km²) is productive
forest, with the remainder a mix of farmland, settlements, and other
uses.
Forests (predominantly spruce, pine, and birch in the Sørmarka
forest areas south of Oslo) dominate higher ground and provide
recreational opportunities, while farmland occupies lower slopes and
valleys. The area supports agriculture, including grains, vegetables,
and livestock, reflecting the moraine-derived soils and relatively
flat-to-rolling terrain.
No major rivers or fjords directly traverse
the town; hydrology consists of small streams, brooks, and scattered
small lakes or ponds that drain toward the Oslofjord. These support
local ecosystems, fishing, and recreational trails (hiking, cycling,
cross-country skiing in winter). Nearby quiet lakes and forest-fringed
areas in Nordre Follo enhance outdoor activities.
Climate
Ski
experiences a humid continental or temperate oceanic-influenced climate
(Köppen Dfb/Cfb transition), moderated slightly by proximity to the
Oslofjord and Skagerrak but more continental than coastal western
Norway. Average annual temperatures range from lows around 19°F (−7°C)
in winter (January) to highs of 69°F (21°C) in summer (July), with
extremes rarely below −18°C or above 26°C. Winters bring snow cover and
sub-freezing temperatures, while summers are mild and pleasant.
Precipitation is moderate (roughly 800–1,000 mm annually, distributed
fairly evenly year-round, with slightly wetter autumns), supporting lush
vegetation and agriculture.
This climate favors cross-country skiing
on local trails in winter and hiking/forestry in other seasons. The low
elevation and inland position result in colder winters and warmer
summers than fjord-side areas further west, but the Oslo region overall
has relatively mild conditions for its latitude due to North Atlantic
currents.
Surrounding Features and Context
Ski borders
Oppegård (west), Enebakk (east), Ås (southwest), and Hobøl (southeast).
To the north lies the greater Oslo metropolitan area; to the south, more
rural Follo landscapes transition toward Vestby and the Oslofjord coast.
The broader Follo district (around 819 km² historically) mixes suburban
development, forests (Sørmarka), and farmland, making Nordre Follo a
commuter belt with green spaces.
Archaeological evidence shows human
settlement dating back ~11,000 years (post-Ice Age), with Stone Age
tools and numerous ancient monuments, indicating long-term suitability
of the landscape for habitation and farming.
The Oslo agglomeration extends into the former Ski municipality. This
applies to the settlement at Langhus, which was previously considered a
separate settlement.
The municipality otherwise consisted of the
towns:
Ski (total of 20,836 inhabitants) Ski agglomeration comprises
of these 6,613 inhabitants in Ås municipality.
Siggerud (1,493
inhabitants)
Kråkstad (1,121 inhabitants)
Skotbu (Wrong town
code/name residents)
Sandvoll (269 inhabitants)
The main industry in Ski municipality was trade and industry. The
municipality was the largest workplace with 1,241 man-years (in 1999).
Many of Ski's residents commute to Oslo for work.
Millennium site
The municipality's millennium venue was the park
area at the Town Hall in Ski.
Twin cities
In the early 1950s,
the Nordic municipalities of Gladsaxe in Denmark, Solna in Sweden and
Ski started a partnership. In 1980, the municipality of Birkala in
Finland joined the collaboration.
Ski Ice Hall
Ski Ice Hall is the 14th ice rink that was built in
Norway. It was opened on 3 December 1987 and is the home ground for the
ice hockey team Ski Icehawks. The hall has 600 standing places for the
public in addition to a café and a cloakroom facility.
