Fredrikstad (help·info) (previously Frederiksstad) (literally Fredrik's Town) is a city and municipality in Østfold county, Norway. The administrative centre of the municipality is the city of Fredrikstad.
The city of Fredrikstad was founded in 1567 by King Frederick II, and established as a municipality on 1 January 1838 (see formannskapsdistrikt). The rural municipality of Glemmen was merged with Fredrikstad on 1 January 1964. The rural municipalities of Borge, Onsøy, Kråkerøy, and Rolvsøy were merged with Fredrikstad on 1 January 1994.
The city straddles the river Glomma where it meets the Skagerrak. Along with neighboring Sarpsborg, Fredrikstad forms the fifth largest city in Norway: Fredrikstad/Sarpsborg. As of 1 January 2013, according to Statistics Norway, these two municipalities have a total population of 128,916 with 75,583 in Fredrikstad and 53,333 in Sarpsborg.
Fredrikstad was built at the mouth of Glomma as a replacement after Sarpsborg (15 km upstream) was burned down by the Swedes. Almost half the population of Sarpsborg stayed behind, and rebuilt their old town at its original site.
The city centre is on the west bank of the Glomma, while the old town on the east bank is Northern Europe's best preserved fortified town.
Fredrikstad used to have a large sawmill industry and was an important harbour for timber export, then later on shipbuilding, until the main yard was closed in the 1980s. The main industries are currently various chemical plants and other light industry.
In 2005, Fredrikstad was the final host port for the Tall Ships' Race, attracting thousands to the city.
General information 
The city was named after the Danish king Frederick II in 1569. The last element stad means "city".
Prior to 1877, the name was spelled Frederiksstad, then from 1877–1888 it was written as Fredriksstad, and finally since 1889 it has been spelled in its current form: Fredrikstad.
The coat-of-arms is from modern times. They were granted on 21 April 1967. The old arms are based on the oldest known seal of the city, which dates from 1610. They showed a fortress being guarded by a bear. Strangely, Fredrikstad had no fortifications in 1610 (it received some at the end of the 17th century). Fredrikstad was founded by citizens of Sarpsborg and both the fortress and the bear are taken from the old arms of Sarpsborg. The composition of the seal was also used as arms since the beginning of the 19th century. The new arms were granted at the 400th anniversary of the city in 1967 and show a more modern variation on the fortress and bear.
After Sarpsborg was burned to the ground during the Northern Seven Years' War, the ruling king, Frederik II of Denmark, decided by royal decree to rebuild the city 15 kilometres (9 mi) south of the original location. This new site's proximity to the sea and the accessible open land surrounding it made it a better location than the old one. The name Fredrikstad was first used in a letter from the King dated 6 February 1569. The temporary fortification built during the Hannibal War (1644–1645) between Sweden and Denmark-Norway, became permanent in the 1660s.
The work on the fortifications was first led by William de Coucheron and later Johan Caspar von Cicignon. During the next 60 years, several fortifications at the Fredrikstad Fortress were built, including Isegran, Kongsten, and Cicignon. In 1735, a suburb on the western side of Glomma, Vestsiden, was founded. This part later grew faster than the old city, and became the dominant city centre. Most of the buildings in the old city burned down during a fire in 1764.
In the 1840s, timber exporting from Fredrikstad started to gain momentum. In the 1860s, several steam powered saws were built along the river, and in 1879 the railway reached Fredrikstad, leading to further growth. With the decline of the timber exports as a result of the modernization of wood-processing industries in the early 1900s, Fredrikstad's production changed to other types of products. It later became one of Norway's most important industrial centres, famous for its large shipyard, Fredrikstad Mekaniske Verksted.
