That’s what Cologne is spending on its theatre, and the bill is rising as the project runs ever later.
It is now scheduled to cost between 554 and 571 million Euros (=dollars) – more than double the original approved estimate – and it will not be finished until well into 2023.
The reasons for the delay? Air conditioning, climate warming, the usual excuses.
The Cologne opera house dates from 1957. Renovation work started in 2012.
Not terribly efficient.
