This was moved from its original location and until this weekend I had failed to locate it. In case you are interested it is now beside the the diving bell. It would appear that someone gave it a polish and part of it now has an ugly orange colour.
Admiral William Brown (also known in Spanish as Guillermo Brown) (22 June 1777 – 3 March 1857) was an Irish-born Argentine Admiral. Brown's victories in the Independence War, the Cisplatine War, and the Anglo-French blockade of the Río de la Plata earned the respect and appreciation of the Argentine people, and today he is regarded as one of Argentina's national heroes. Creator and first admiral of the country's maritime forces, he is commonly known as the "father of the Argentine Navy"
