#DublinBay - "How many capital cities can boast such a rich marine megafauna?" asks the Irish Whale and Dolphin Group's Dr Simon Berrow.
It's an important question as Dublin last week celebrated 300 years of profound change since the decision to build the Great South Wall.
Along with the Bull Wall that followed in the 1800s, it was a project intended to solve dangerous silting in the main channel to Dublin Port.
But together, they completely reshaped the environment around Dublin Bay into a habitat for hundreds of species of marine wildlife - including the aforementioned megafauna like dolphins and porpoises that frequent Dublin's waters.
And it's an environment that's still reshaping today, as the Irish Independent reports - using the example of a toilet block built on Bull Island's Dollymount Strand in the early 1970s but which today, only 44 years on, is nestled deep in the dunes some distance from the beach.
Bull Island itself, which did not exist before the building of the Bull Wall two centuries ago, is now home to nine distinct habitats among the many important sites that round the bay from Howth's sea cliffs to Seapoint's rocky shoreline.
And its biosphere status is one that Dublin City Council wants to extent over an area from Malahide down to Killiney to ensure the bay's proper protection and management.
