Well, Their Royal Highnesses Crown Prince Frederik and Crown Princess Mary of Denmark are still in awesome Brazil and today the couple made their rounds in Rio de Janeiro.
So what did they do? The crown prince and his Danish business delegation visited the oil company, Pentrobas, attended the opening of a water seminar, and attended a reception at the Danish IT company, Danmagi. At 3pm the crown prince bolted on over to the Rio Oil and Gas Exhibition to visit the “… official Danish pavilion at the exhibition.” Whilst there he “…inspected Danish companies’ booths.” Interesting.
Meanwhile, Crown Princess Mary visited the Cidade de Deus youth center, and then drove to the Pontifical Catholic University where she was given a tour of the campus. Later on she participated in a seminar at the university regarding “… the exchanges and cooperation between Danish and Brazilian universities.”
In the late afternoon, the crown princely couple attended yet another reception held in their honor with the Danish colony and were received by the President of the Danish-Brazilian Chamber of Commerce, Mr. Knud Bach.
At the end of day, Crown Prince Frederik and Crown Princess Mary were hungry so they ate dinner with a bunch people from various Danish and Brazilian companies.
And, that’s it.
