Prince Charles, heir to the UK throne, joined ceremonies on Germany's traditional day of war remembrance on Sunday.
Masked and wearing the customary poppy, Prince Charles arrived in Berlin with his wife Camilla, the Duchess of Cornwall, late on Saturday.
Britain and Germany were enemies in the First and Second World Wars but have since forged close diplomatic, economic and military ties.
The royal couple were received on Sunday by German President Frank-Walter Steinmeier and his wife, Elke Buedenbender, at Bellevue Palace.
The British royal couple will observe the traditional wreath-laying ceremony at Berlin's Neue Wache. Originally designed as a site to commemorate those who died in the Napoleonic Wars, it is now Germany's Central Memorial for the Victims of War and Tyranny.
The eldest son of Queen Elizabeth II later spoke at a memorial event at the Bundestag, Germany's parliament.
The latest trip by Prince Charles, who has visited Germany more than 30 times since 1962, came with Britain and the EU locked in talks over a post-Brexit trade deal.
