Brno is one of the larger cities in the southern (or Monrovia) region
of Czech Republic. The population flourished during the Soviet rule of
the country, starting in the 1950s, when the Soviet government opted to
greatly expand the industrial role of this community. By quickly building
modest concrete apartments, the town had an instant work population to
service newly constructed factories and industries.
The red-roof homes are those built before Soviet rule (and as such,
still had some color to them).
The Soviets were known for hastily built housing, typically concrete,
with a shelf life of about 30 years.
Now 30+ years later, some have been saved -- and painted colors
-- while others are torn down.
Light industry is part of the role of Brno during the Soviet control
of the community...
... as well as other industries. The workers lived in the gray concrete
apartments for next to nothing.
With the fall of Communism and the Iron Curtain in 1989, other businesses
began to pop up.
