The Oktoberfest, or Wiesn to the locals, is rebuilt, every year, from the ground up.   Every tent, ride, stall, and table is brought back to the festival grounds and reconstructed.   This is considered a major engineering and logistical feat.  Essentially they rebuild a city for 6M+ people with all the infrastructure and buildings in 82 days to open on time.

Did you know, they rebuild the entire Oktoberfest (every tent, stall, ride, and service) from bare dirt each year?

It is considered a massive construction and engineering feat.
