You are looking at Port Adelaide’s most arresting (and “enigmatic”)  21st century structure.

You may be relieved to know that it has nothing to with nuclear power!

As a construction industry journal headline put it, on the 2nd day of February 2023:

As reported in the above video, no persons were physically injured.

Remarkably, only four weeks later, a replacement was safely erected.

The Domesilo can store up to 47,000 tonnes of dry cement.
