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:
Angelokastro is a Byzantine castle on the island of Corfu. It is located at the top of the highest peak of the island"s shoreline in the northwest coast near Palaiokastritsa and built on particularly precipitous and rocky terrain. It stands 305 m on a steep cliff above the sea and surveys the City of Corfu and the mountains of mainland Greece to the southeast and a wide area of Corfu toward the northeast and northwest.
Angelokastro is one of the most important fortified complexes of Corfu. It was an acropolis which surveyed the region all the way to the southern Adriatic and presented a formidable strategic vantage point to the occupant of the castle.
Angelokastro formed a defensive triangle with the castles of Gardiki and Kassiopi, which covered Corfu"s defences to the south, northwest and northeast.
The castle never fell, despite frequent sieges and attempts at conquering it through the centuries, and played a decisive role in defending the island against pirate incursions and during three sieges of Corfu by the Ottomans, significantly contributing to their defeat.
During invasions it helped shelter the local peasant population. The villagers also fought against the invaders playing an active role in the defence of the castle.
The exact period of the building of the castle is not known, but it has often been attributed to the reigns of Michael I Komnenos and his son Michael II Komnenos. The first documentary evidence for the fortress dates to 1272, when Giordano di San Felice took possession of it for Charles of Anjou, who had seized Corfu from Manfred, King of Sicily in 1267.
From 1387 to the end of the 16th century, Angelokastro was the official capital of Corfu and the seat of the Provveditore Generale del Levante, governor of the Ionian islands and commander of the Venetian fleet, which was stationed in Corfu.
The governor of the castle (the castellan) was normally appointed by the City council of Corfu and was chosen amongst the noblemen of the island.
Angelokastro is considered one of the most imposing architectural remains in the Ionian Islands.
