Charles I in Three Positions

The Windsor Castle Royal Tattoo was an annual military tattoo held in the private grounds of Windsor Castle by permission of Queen Elizabeth II, from 2008 to 2011. The event's proceeds went to the Royal British Legion to help support recently returned troops from battle. The Tattoo website described itself as: ...a celebration of the capabilities of today’s forces through music and action. It is a tri-service event and has a packed programme of international and British military acts, massed bands, pipes and drums, modern military re-enactments and a fantastic finale.....The Tattoo tells the story of modern life in each of the services (the Army, the Royal Air Force and the Royal Navy) and large screens show footage from each of the services in action in war zones, taking the audience to the current operational environment.The Windsor Tattoo was similar to the Royal Tournament, the world's largest military tattoo which was axed by the British Government in 1999. In 2009 the Tattoo saw the return of the Royal Navy Field Gun Race 10 years after it was laid to rest along with the Royal Tournament.

On 9 April 2021, Prince Philip, Duke of Edinburgh, the husband of Queen Elizabeth II of the United Kingdom and the other Commonwealth realms, and the longest-serving royal consort in history, died of old age at Windsor Castle at the age of 99, two months before his 100th birthday.The death of the Duke set in motion Operation Forth Bridge, a plan detailing procedures including the dissemination of information, national mourning, and his funeral. The Duke had indicated wishes for a smaller funeral, though amendments were still made to the plan to bring his service in line with COVID-19 regulations, including quarantine for members of the Duke's family travelling from abroad. A thanksgiving service attended by politicians and foreign royalty was held at Westminster Abbey on 29 March 2022, which included elements that could not be implemented in the funeral ceremony due to COVID-19 restrictions. His funeral took place on 17 April 2021. Representatives of nations and groups around the world sent condolences to the Queen, the royal family, and citizens of the Commonwealth. Flowers and messages of condolence were left by the public at Buckingham Palace and Windsor Castle, with members of the royal family publicly paying tribute to the Duke in the days after his death.

Windsor Castle is a royal residence at Windsor in the English county of Berkshire. It is strongly associated with the English and succeeding British royal family, and embodies almost a millennium of architectural history. The original castle was built in the 11th century, after the Norman invasion of England by William the Conqueror. Since the time of Henry I (who reigned 1100–1135), it has been used by the reigning monarch and is the longest-occupied palace in Europe. The castle's lavish early 19th-century state apartments were described by early 20th century art historian Hugh Roberts as "a superb and unrivalled sequence of rooms widely regarded as the finest and most complete expression of later Georgian taste". Inside the castle walls is the 15th-century St George's Chapel, considered by the historian John Martin Robinson to be "one of the supreme achievements of English Perpendicular Gothic" design.Originally designed to project Norman dominance around the outskirts of London and oversee a strategically important part of the River Thames, Windsor Castle was built as a motte-and-bailey, with three wards surrounding a central mound. Gradually replaced with stone fortifications, the castle withstood a prolonged siege during the First Barons' War at the start of the 13th century. Henry III built a luxurious royal palace within the castle during the middle of the century, and Edward III went further, rebuilding the palace to make an even grander set of buildings in what would become "the most expensive secular building project of the entire Middle Ages in England". Edward's core design lasted through the Tudor period, during which Henry VIII and Elizabeth I made increasing use of the castle as a royal court and centre for diplomatic entertainment. Windsor Castle survived the tumultuous period of the English Civil War, when it was used as a military headquarters by Parliamentary forces and a prison for Charles I. At the Restoration of the monarchy in 1660, Charles II rebuilt much of Windsor Castle with the help of the architect Hugh May, creating a set of extravagant Baroque interiors. After a period of neglect during the 18th century, George III and George IV renovated and rebuilt Charles II's palace at colossal expense, producing the current design of the state apartments, full of Rococo, Gothic and Baroque furnishings. Queen Victoria made a few minor changes to the castle, which became the centre for royal entertainment for much of her reign. It was used as a refuge by the royal family during the Luftwaffe bombing campaigns of the Second World War and survived a fire in 1992. It is a popular tourist attraction, a venue for hosting state visits, and was the main residence of Queen Elizabeth II from 2011 to 2022.

A bronze equestrian statue of King Charles II on horseback sits in the Upper Ward of Windsor Castle beneath the castle's Round Tower. It was inspired by Hubert Le Sueur's statue of Charles I in London, the statue was cast by Josias Ibach in 1679, with the marble plinth featuring carvings by Grinling Gibbons. The statue was commissioned by Tobias Rustat, Charles's valet. Rustat was a significant philanthropist of the 1670s. Rustat's fortune was partially derived from the transatlantic slave trade, having been an investor in the Royal African Company.The rear left hoof of the horse is inscribed 'Josias Ibach Stada Bramesis 1679 FUDIT'. Gibbons had been appointed the 'Surveyor and Repairer of Carved Work at Windsor' in 1682. The Royal Collection Trust listing for the statue describes the design as "very innovative" in its depiction of Charles as a Roman emperor with its absence of traditional symbols of the British monarchy such as the Order of the Garter. Charles is depicted wearing a suit of armour in a classically Roman style, without spurs and stirrups for his horse. He is crowned with a laurel wreath. The statue started a subsequent trend for British monarchs to be portrayed in a Roman style.The statue may have been inspired by the Equestrian Statue of Marcus Aurelius that was originally situated on the Capitoline Hill in Rome with its similar placing of the horse and design of the plinth.

The Print Room at Windsor Castle is a print room which is an office in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom.

A large part of the Old Master drawings were acquired by George III.

Queen Mary's Dolls' House is a dollhouse built in the early 1920s, completed in 1924, for Queen Mary, the wife of King George V. It was designed by architect Sir Edwin Lutyens, with contributions from many notable artists and craftsmen of the period, including a library of miniature books containing original stories written by authors including Sir Arthur Conan Doyle and A. A. Milne.

On 20 November 1992, a fire broke out in Windsor Castle, the largest inhabited castle in the world and one of the official residences of the British Monarch. The castle suffered extensive damage and was fully repaired within the next five years at a cost of £36.5 million, in a project led by the conservation architects Donald Insall Associates. It led to Queen Elizabeth II paying tax on her income, and to Buckingham Palace, the former monarch's other official residence, being opened to the public to help pay for the restoration work. This event was part of what Queen Elizabeth II called her annus horribilis.

The office of Royal Librarian, in the Royal Collection Department of the Royal Household of the Sovereign of the United Kingdom, is responsible for the care and maintenance of the books and manuscripts in the Royal Library, a collection spread across all the palaces, occupied and unoccupied. In addition to his or her role overseeing the librarians in the Royal Library, the Librarian is also Deputy Keeper of the Royal Archives and is responsible for the management of the Royal Archives and its collections.

St George's Chapel at Windsor Castle in England is a castle chapel built in the late-medieval Perpendicular Gothic style. It is both a Royal Peculiar (a church under the direct jurisdiction of the monarch) and the Chapel of the Order of the Garter. St George's Chapel was founded in the 14th century by King Edward III and extensively enlarged in the late 15th century. It is located in the Lower Ward of the castle. The castle has belonged to the monarchy for almost 1,000 years and was a principal residence of Elizabeth II before her death. The chapel has been the scene of many royal services, weddings and burials – in the 19th century, St George's Chapel and the nearby Frogmore Gardens superseded Westminster Abbey as the chosen burial place for the British royal family. The running of the chapel is the responsibility of the dean and Canons of Windsor who make up the College of Saint George. They are assisted by a clerk, verger and other staff. The Society of the Friends of St George's and Descendants of the Knights of the Garter, a registered charity, was established in 1931 to assist the college in maintaining the chapel.
