It was quite common in the 17th century for citizens in the Mälaren valley to invest in the iron industry. The first bar-iron forge at Trångfors was established in 1628 by Adolf Willemson, a merchant from Västerås. It started off small, with just three workers.
In the latter half of the 18th century, the Strömsholm canal cut straight across the Trångfors estate and the old manor house had to be pulled down. The existing forge was built in 1799. Good use was made of the water from the canal: an enclosed timber trough from the canal provided water power for the forge hammer. When the Lancashire method was introduced in 1875, production rose sharply and peaked in 1900 at an annual output of 3,100 tonnes. But by 1915, the forge had been closed down.
One of the four Lancashire furnaces has been restored, and work is under way on the water-wheel and trough. The mumbling hammer has been given a new base. In time, the intention is to be able to demonstrate the pig-iron refining process and mixing of the melt in the forge.
A congenial room with a cosy open fire is available for hire for private functions and meetings. It has been set up in the former spark-machining workshop next door to the forge.
A room above the forge, which used to be a rest room for the forge workers between shifts, has now been converted into a meeting room. The murals on the walls were painted by Gunnar Hall. Next door to that is the charcoal storehouse, which dates from 1800. The charcoal wagons ran straight in here and tipped their load from the ramps at the top of the furnace.
The Trångfors power station on the other side of the river was built in 1898–9 by a firm of consulting engineers, Qvist & Gjers, of Arboga. A water trough was built at the side of the waterfall and it carried the water over a distance of several hundred metres to the works. The power station operated until 1988 and is now a museum. The original equipment has been preserved. The station has six horizontal turbines each generating an output of 400 hp. The generators were manufactured by ASEA and were awarded the “Grand Prix” at an international industrial exhibition in Paris in 1900.
Every August, there is a Trångfors open day when the building is open to visitors, who can also watch barges being locked through on the canal.References:
Glimmingehus is the best preserved medieval stronghold in Scandinavia. It was built 1499-1506, during an era when Scania formed a vital part of Denmark, and contains many defensive arrangements of the era, such as parapets, false doors and dead-end corridors, 'murder-holes' for pouring boiling pitch over the attackers, moats, drawbridges and various other forms of death traps to surprise trespassers and protect the nobles against peasant uprisings. The lower part of the castle's stone walls are 2.4 meters (94 inches) thick and the upper part 1.8 meters (71 inches).
Construction was started in 1499 by the Danish knight Jens Holgersen Ulfstand and stone-cutter-mason and architect Adam van Düren, a North German master who also worked on Lund Cathedral. Construction was completed in 1506.
Ulfstand was a councillor, nobleman and admiral serving under John I of Denmark and many objects have been uncovered during archeological excavations that demonstrate the extravagant lifestyle of the knight's family at Glimmingehus up until Ulfstand's death in 1523. Some of the most expensive objects for sale in Europe during this period, such as Venetian glass, painted glass from the Rhine district and Spanish ceramics have been found here. Evidence of the family's wealth can also be seen inside the stone fortress, where everyday comforts for the knight's family included hot air channels in the walls and bench seats in the window recesses. Although considered comfortable for its period, it has also been argued that Glimmingehus was an expression of "Knighthood nostalgia" and not considered opulent or progressive enough even to the knight's contemporaries and especially not to later generations of the Scanian nobility. Glimmingehus is thought to have served as a residential castle for only a few generations before being transformed into a storage facility for grain.
An order from Charles XI to the administrators of the Swedish dominion of Scania in 1676 to demolish the castle, in order to ensure that it would not fall into the hands of the Danish king during the Scanian War, could not be executed. A first attempt, in which 20 Scanian farmers were ordered to assist, proved unsuccessful. An additional force of 130 men were sent to Glimmingehus to execute the order in a second attempt. However, before they could carry out the order, a Danish-Dutch naval division arrived in Ystad, and the Swedes had to abandon the demolition attempts. Throughout the 18th century the castle was used as deposit for agricultural produce and in 1924 it was donated to the Swedish state. Today it is administered by the Swedish National Heritage Board.
On site there is a museum, medieval kitchen, shop and restaurant and coffee house. During summer time there are several guided tours daily. In local folklore, the castle is described as haunted by multiple ghosts and the tradition of storytelling inspired by the castle is continued in the summer events at the castle called "Strange stories and terrifying tales".
