Since 1991, the Museum of Contemporary Art has enthralled, inspired and confused Sydneysiders and tourists of all kinds. Established through a bequeathment of money from Australian artist John Power (who died in 1943, making it one very long inheritance battle), the MCA has recently undergone a much publicised redevelopment during which ruins of a colonial dockyard were discovered underground. But contrary to what you might think, their art deco building wasn’t just an attempt by the MCA itself to be trendy – they weren’t in there first.

It’s funny that despite the expensive and lengthy redevelopment process, they missed this little clue. In fact it appears it was covered up by another sign for years and only recently disturbed. As you can see, it reveals that the MCA’s building was once the site of the MSB. This is apparently common knowledge, but what was the MSB?

It makes sense that the Maritime Services Board was established in and housed at the Rocks. 90 years of confusing yet important Sydney port control laws and services were consolidated into one administrative entity, the MSB, in 1936. In 1949 construction began on the building, which was completed in 1952, so even by art deco standards it was late to the party. The MSB itself relocated in 1989, leaving behind the building for the art world to work its magic on and in. It’s just that you missed this spot, guys. Then again, knowing the MCA, maybe it’s actually one of the exhibits and I just don’t get it.
