TRH are shown artefacts and manuscripts during a visit to the Musikverein concert hall
The Prince of Wales and The Duchess of Cornwall have spent two days in Austria as part of the Royal visit after arriving in Vienna on Wednesday evening.
To begin the visit, Their Royal Highnesses were taken on a behind-the-scenes tour of Cafe Demel, one of Vienna's treasured coffee houses.
The Prince and The Duchess were shown the test used by pastry chefs making the perfect apple strudel and were asked to read a copy of a newspaper through a gossamer thin sheet of pastry.
Their Royal Highnesses watched as Head Chef Oliver Csapo and his team made the cafe's signature apple strudel, Sacher Torte and hand-made tea and cheese biscuits. Upstairs in the café, The Prince sat down with a cup of tea and had a chat with some of the café’s apprentices.
Founded in 1786, the cafe carries the title K&K Hofzuckerbackerei, a royal warrant dating to the time of the Habsburg Monarchy, which fell at the end of the First World War after ruling Central Europe for 600 years.

In the evening, The Prince and The Duchess were guests of honour at a State Banquet staged at Vienna's Hofburg Palace. There were around 100 guests at the event hosted by Austria's President Alexander Van der Bellen.
The next day, The Prince of Wales and The Duchess of Cornwall met British and Austrian survivors of Nazi persecution when they toured the city's Jewish Museum.
Holocaust survivor Gerda Frei, 80, said: "It is wonderful that The Prince and Duchess came here."
"The Prince told us how proud he was of his grandmother, Princess Alice of Greece, who hid a Jewish family from the Nazis.”
Later, Their Royal Highnesses listened to Beethoven's Ninth Symphony played by the Vienna Philharmonic at the Austrian capital's famous Musikverein.
Conductor Christian Thielemann led the orchestra in a rehearsal ahead of its appearance at the Salzburg Easter Festival.
The neo-classical concert hall, opened in 1870, is one of Vienna's treasures and has connections to some of the world's greatest composers.
Downstairs, Dr Otto Bieber, Head of the Archive, showed Their Royal Highnesses original manuscripts by Mozart and Beethoven.
The Prince and The Duchess then visited Weinbau Buscheschank Obermann vineyard where they were given a tour of the family business and tasted local food and wine.

The Royal couple were introduced to several wines by Martin Obermann, owner of the vineyards, and his son Lorenz, 19, who was translating.
The family have owned the vineyard for five generations and use no chemicals on their plants, explaining: "We want to leave healthy nature for future generations."
Their Royal Highnesses went on to try a selection of local produce, including cured meats, cheeses and bread.
Before departing Austria, The Duchess visited the Spanish Riding School which has practised classical equitation for over 450 years, longer than any other riding institution.
The Prince meanwhile visited the headquarters of the Austrian Integration Fund to learn about their work and meet refugees. His Royal Highness took part in roundtable discussions centred around tackling modern slavery and human trafficking.
