Fiskars is the best known of a number of ironworks villages that were established in the early 17th century to the Pohja area. A crushing mill was established by the lower rapids in 1649, with a blastfurnace on the opposite bank. The founder of Fiskars ironworks was the Dutch businessman Peter Thorwöste, who was allowed by Queen Christina of Sweden to manufacture cast iron and forged products, with the exception of cannons.
The Russian occupation of Finland (the Great Wrath) affected also Fiskars. Nearby was a center of Russian civilian and military administration, and in 1713 the ironworks at Fiskars and Antskog were plundered and wrecked by the Russians.
The heyday in the history of Fiskars began in 1822 when it was bought by Johan Julin (1787-1853). Under Julin, work at the ironworks focused on refining iron. The ironworks and the village of Fiskars started to grow quickly. In 1850 there were about 500-600 employees and the total number of inhabitants was approximately 1400. Throughout the period from into the 1960s, Fiskars purchased several works and companies in the steel business. In the 20th century the industrial operations required more up-to-date facilities, production was moved to Billnäs.
Today there are many workshops and boutiques providing Finnish handicrafts, arts and design thoughout the Fiskars village and visitors can spend time just wandering around in the beautiful ironworks area.
Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
