What is the most inhabited castle in the world?

Windsor Castle is the oldest and largest inhabited castle in the world and has been the family home of British kings and queens for almost 1,000 years. It is an official residence of Her Majesty The Queen and is still very much a working royal palace today, home to around 150 people.



The most inhabited castle in the world is Windsor Castle, located in the English county of Berkshire. As of 2026, it remains the oldest and largest occupied castle globally, having been a royal residence for nearly 1,000 years. Founded by William the Conqueror in the 11th century, it has housed 40 monarchs. While it serves as a formal palace for King Charles III for state occasions, it is a living community home to around 150 people. These residents include the Constable and Governor of the Castle, the Dean of Windsor, Military Knights, and various staff members who keep the massive estate running. Its dual role as a high-security royal fortress and a bustling home makes it unique. Unlike many historic castles that function primarily as museums, Windsor remains a working palace with a full-time population, continuing its legacy as a vibrant center of British royal life and heritage.
