At one time, hundreds of people used to work in this factory and it was an important part of the economy in the Briton Ferry area.
However, it is now a derelict building which is said to have become a fire risk.
Inside the factory, which has been empty for more than 20 years, the walls are covered in graffiti and big chunks of its roof are missing.
There were hopes for a bright future for the site but they were dashed when the owners went into administration, leaving the frame of the building to deteriorate and making the factory a target for fly-tipping.
Wern Works - nestled between the Old Briton Ferry bridge, the canal and the River Neath - was built in the late 1940s following a death-blow to several older tinplate works.
However, the long established metal working industry in the town continued when the site was transformed into a modern aluminium works.
The factory was equipped to roll aluminium sheet, especially for the transport and aircraft industry.
Throughout the 1950s and 1960s, the plant was owned and run by metal manufacturer High Duty Alloys, which bought the nearby Vernon House and turned it into offices and a conference centre - which closed in the 1970s.
The plant was later taken over by a Swiss aluminium company called Alusuisse, which continued to operate Wern Works until the early 1990s, when it completely closed.
At its peak, Wern Works - which was the last metal producing plant to operate in Briton Ferry - created hundreds of local jobs.
One of its proudest products was creating aluminium material for the wings of Concorde, the first supersonic passenger-carrying commercial airplane, built jointly by aircraft manufacturers in Great Britain and France.
Sadly, it has now become an eyesore and a hotspot for flytipping.
In 2016, Michael Cuddy, of the Cuddy Group, got planning permission to demolish the old works and develop the site into a waste transfer facility. However, that never happened and Cuddy Group folded in July, 2018.
There have been a number of fires reported at Wern Works in recent years, including an incident in 2018 where thick black smoke was sent over Briton Ferry from a tyre fire there.
In 2019, authorities said that dumped waste was being set on fire at Wern Works "up to three times a month", and a large quantity of the potentially explosive chemical acetone was found in drums at the site sparking an emergency response by Natural Resources Wales.
More than 200 people from all over the UK descended on the disused factory for an all-night rave in March, 2020, and residents were "terrorised" by the noise and loud music coming from the party.
Councillor Chris James, who represents Briton Ferry East, went to Wern Works to break up the rave, and said it was "terrorising the residents".
At the time he said: "This was not only extremely annoying in that it kept hundreds of people awake in Briton Ferry all night, it was also very dangerous.
"The old Wern Works itself represents a danger but to have around 200 people in there without any safety arrangements whatsoever was quite shocking."
