Moskvarium

This guide to Moskvarium in Moscow starts with a strange, late-night discovery in 2013 on the grounds of Moscow's old Soviet exhibition park, when activists heard splashing and a chirping call that didn't belong in the city. It traces how two orcas ended up hidden in temporary tanks years before the oceanarium itself had walls or a name, all before it finally opened in August 2015. Listen for the echo of that first splash the next time the water goes still.
