The King is to visit Poland to mark the 80th anniversary of the liberation of the former Nazi concentration camp Auschwitz-Birkenau.
Charles will travel to Poland to join other dignitaries and Holocaust survivors invited to a service, held at the Auschwitz-Birkenau museum and memorial, commemorating the milestone.
Ahead of the event next Monday, Charles will meet members of the local community in Krakow, Buckingham Palace has said.
The King will also meet Poland’s President Andrzej Duda during his brief visit.
The trip will be the King’s fifth to Poland. More recent visits included one in 2008 with his wife the Queen, and in 2010 as part of a wider European tour which also took in Hungary and the Czech Republic.
