Sadly, it's probably just a really interesting icy outcrop of some description. Current theories of Ceres' composition suggest an enormously thick icy layer covered in dust and rock, so a meteor strike could expose the ice (and probably cause all kinds of weird physics --- ice goes strange under extreme temperatures and pressures).
But let's say it is aliens, and in a week or so we get pictures of what is indubitably an alien city.

Thought experiment: what happens next?
