That is HMCS Athabascan in port at Charleston Harbour.

The cobblestone has an interesting story.  When British ships were hauling goods from the colonies, they made the trip back to the new world empty.  To make them stable, they put ballast stones in the holds of their ships.  These stones were then dumped and replaced with the goods bound for England.

When the crown discovered that their discarded stones were being used to paved street, there was a tax imposed on them too.
