Britain's King Charles III on Friday commemorated German victims of World War II Allied air raids, a gesture carrying great significance for both countries.
On the third and final day of his first state visit since ascending the throne, the monarch, accompanied by German President Frank-Walter Steinmeier, visited the St Nikolai memorial in Hamburg, where he laid a wreath.
The move, in the ruins of a church, is unprecedented for a British sovereign. TV commentators on rolling news channel NTV calling it a "great, great symbol".
When Charles's late mother, Queen Elizabeth II, visited Dresden in 1992, eggs were flung at her after she failed to get out of her car to lay a wreath at the rubble of the Frauenkirche -- a symbol of wartime destruction.
After laying the wreath alongside Steinmeier and Hamburg mayor Peter Tschentscher, Charles stood for a moment with his head bowed.
Then Queen Consort Camilla placed a white rose at the memorial.
Ahead of the ceremony, Germany's biggest-selling daily Bild said Charles' gesture at the memorial "will say more than any speech".
The issue of German suffering in World War II is historically and politically explosive.
Wracked with guilt over the extermination by the Nazis of six million Jews, mainstream Germany tends to shy away from discussing the suffering of Germans during the war.
The WWII air raids, which were among the most controversial actions taken by the Allies, were designed to terrorise the German population and force a surrender. They killed tens of thousands of civilians.
Hamburg's bishop Kirsten Fehrs, who said the Coventry Litany of Reconciliation at Friday's ceremony, stressed the importance of the event.
"The sign of reconciliation between two war enemies and the joint commemoration of the victims are an important signal today," she said, according to remarks carried by regional broadcaster NDR.
Engineer Rainald Erbacher, 54, who was at the memorial said Charles' action "sends a positive signal".
He underlined that it was a "difficult balance to strike between the past and looking ahead" but that the king's gesture was appropriate.
It was important attention to "the legacy of our ugly past", said rural tour guide Chrissi Breyer, 55, who was among hundreds of well-wishers who waited in the rain outside Hamburg city hall to catch a glimpse of Charles.
The king, who was greeted with cheers by the crowd, had set an "example" with his gesture, Breyer said.
Hamburg and Dresden were among the most heavily bombed cities in Nazi Germany.
On July 24, 1943, Britain and the United States began raiding Hamburg in what was described as a "Blitz week", with the Royal Air Force striking by night and the US forces bombing by day.
Codenamed Operation Gomorrah, it unleashed some 9,000 tonnes of explosives, killing more than 30,000 people and leaving the port city in rubble.
Originally designed by English architect George Gilbert Scott, who restored London's Westminster Abbey, St Nikolai has been left in its ruined state and now houses a WWII memorial and museum.
The themes of reconciliation and a future forged by common values have featured prominently during Charles's three-day visit, widely interpreted as a bid to build bridges after Brexit.
But during his inaugural foreign trip as king, he managed to score several firsts, including becoming the only monarch to address the German parliament.
In Berlin for the first two days of his visit, he also interacted with well-wishers at the Brandenburg Gate where he was given a formal welcome, as well as toured a reception centre for Ukrainian refugees.
The royal couple travelled on Friday morning to Hamburg on a regular scheduled train, to the delight of some passengers.
Medical student Henriette Czech, 20, was surprised to find herself using the same means of transport as the monarch.
"It's exciting for a mere mortal that a royal is on the train," she told AFP.
