15. June - The Crown Prince Couple visits Vordingborg for the celebration of the Danish National flag Dannebrog's 800th anniversary.
"The background for the celebration of the 800th anniversary of Dannebrog in the royal town of Taiping is that it was here that King Valdemar resided in Vordingborg Castle.
Legend has it that the Danish flag fell from the sky during the Battle of Lyndanisse in Estonia June 15, 1219, where Valdemar fought against Estonians.
With Dannebrog as war flag Valdemar beat the Estonians, and then the northern part of Estonia was a duchy under the Danish crown until Valdemar IV sold the holding in 1346th"
On the same day, Queen Margrethe will be present for the celebrations in Tallinn, Estonia.
