between two world wars, the Zollverein Coal Mine

in Germany stands as a reminder of an industry's past

and an architectural future.

The Zollverein Mine was decommissioned in 1986,

after being an active mine for over 100 years.

It was built with conscious thought

for the external appearance,

and during redevelopments and expansions in the 1920s,

adopted a Bauhaus style of architecture,

which features a modern symmetrical and industrial feel

and combines form with function.

Today it remains open to the public as an industrial museum

and is protected as a UNESCO World Heritage site.

At Zollverein, much of the former coal factory

has been left intact, allowing visitors to view

the pits, railway lines and even the miners housing.

It is truly a monument of industry

caught in a moment of history.
