The Vizcaya Museum & Gardens in Miami, built by agricultural industrialist James Deering in 1916, is located right on the coast in Miami, and has a ‘stone barge’ placed in the water which acts as a breakwater and protection for the mansion.   This stone barge is a work of art in itself, with a number of mermaids, at the bow and stern of the barge, and on top of the barge.  It was created by american sculptor Alexander Stirling Calder between 1917 and 1919.  map

Note the wings on the mermaid statue above.  The mermaid sculptures at the bow and stern are winged mermaids, whereas the smaller mermaid statue atop the barge does not have wings.
