Archive: Port Talbot steel-making in 1964

The town of Port Talbot has for more than 60 years been synonymous with steel.

The sprawling works span the horizon as you drive along the M4.

In its heyday in the 1960s, nearly 20,000 people worked there. The town grew up around it.

Numbers may have dwindled but even with a 4,000-strong workforce, it still has an imposing presence in the Welsh economy.

Here is archive film inside the plant in the mid 1960s - before it was privatised. It was part of a BBC programme for schools explaining how Port Talbot steel was made.
