President Donald Trump laid a wreath at the tomb of the late Queen Elizabeth II during a private, ten‑minute visit to St George’s Chapel at Windsor Castle on Wednesday, describing the moment as a "great honour."

The visit, part of the opening day of the US president’s second state visit to the United Kingdom, was a closed moment of reflection. Trump and the First Lady were accompanied inside the chapel by Chapter Clerk Charlotte Manley and Dean of Windsor the Reverend Christopher Cocksworth, who showed them royal tombs and artifacts before the pair emerged to a musical performance by choristers of St George’s Chapel.

After the private wreath‑laying at the King George VI Memorial Chapel, Trump spent time touring the chapel’s historic sites, including the tomb of Henry VIII and Sir Winston Churchill’s Garter Plate, Manley said. Officials said no photographs or footage of the ten‑minute private moment would be shared. The president later led applause for the choir and posed for photographs with its members.

The public ceremonial welcome at Windsor included an inspection of a bespoke Guard of Honour by Trump, who inspected the troops alongside King Charles III. The inspection was followed by a carriage procession through the Windsor estate and a 41‑round gun salute fired by The King’s Troop Royal Horse Artillery, with a second salute staged at the Tower of London. Organisers said roughly 1,300 members of the British armed forces, and some 120 horses, took part — a scale described by officials as the largest military ceremonial welcome for a state visit to the UK in living memory.

Trump and the royal party watched a Beating Retreat musical display by 200 military musicians on the East Lawn, and were due to be treated later to a flypast involving the Red Arrows alongside UK and US F‑35 aircraft. The two countries also planned a state banquet at Windsor Castle in the evening, where both the King and the president were scheduled to give speeches.

Earlier at Windsor, the Trumps were shown items from the Royal Collection relating to the United States in the Green Drawing Room. Royal librarians displayed letters and maps, including Georgian papers and correspondence from King George III and Abraham Lincoln that officials said had been requested by the president. Trump was reported to have reacted enthusiastically to the documents, saying they were "the real deal." The visit to the exhibits followed a private lunch in the State Dining Room.

Gifts were exchanged in line with diplomatic tradition. Their Majesties presented the president with a Union Flag that flew above Buckingham Palace on the day of his inauguration and a bespoke leather volume commemorating the 250th anniversary of the Declaration of Independence. The Trumps presented King Charles with a replica of a Presidential Eisenhower sword, and other reciprocal gifts were announced for members of the royal household.

The state visit takes place against a backdrop of protests and heightened security. Metropolitan Police and Thames Valley officers deployed more than 1,600 officers across London and Windsor, and organisers warned of as many as 50 protest groups expected to demonstrate in central London during the two‑day visit. Authorities said four people were arrested on suspicion of malicious communications after images were projected onto Windsor Castle, and two people were detained over alleged airspace breaches related to the visit.

Campaign groups and political figures expressed a range of views. Demonstrations included activists calling for action on climate and human rights issues, while supporters of the president gathered outside Windsor. Several public figures announced a boycott of the state banquet in protest of Trump’s policies on Gaza.

The visit also coincides with a raft of UK‑US economic and technology announcements. Downing Street and White House officials unveiled a "tech prosperity" agreement aimed at deeper cooperation on artificial intelligence, quantum computing and nuclear power, accompanied by multibillion‑pound investments from US technology companies, including a major commitment from Microsoft. British and US officials described the pact as a step change in bilateral economic relations.

White House and British officials said no public‑facing engagements were planned for the president while in Windsor, and that the itinerary was primarily ceremonial and diplomatic. Trump was due to hold talks with Prime Minister Sir Keir Starmer at Chequers on Thursday. The government said the visit was intended to reinforce the "special relationship" and to advance security, trade and technological collaboration between the two countries.

The first day of the state visit underscored both ceremonial ties and political sensitivities. The royals and the president kept largely to protocol during the public elements of the programme, while organisers and security services managed competing demands for visibility and protest across the capital. The trip will continue with further meetings, military demonstrations and formal receptions intended to cement diplomatic and commercial ties between London and Washington.
