Construction of Windsor Castle

Windsor Castle began as a wooden fort perched atop a man-made hill for strategic defence. Over the next century, monarchs replaced the wooden structures with stone walls and towers, using locally sourced Bagshot Heath stone for durability and strength.

Construction continued in phases over the centuries:

  • Edward III (14th century): Transformed the castle into a Gothic palace, creating luxurious royal apartments arranged around courtyards.
  • St George’s Chapel (1475–Henry VIII): Begun by Edward IV and completed under Henry VIII, the chapel features soaring vaulted ceilings and intricate stonework.
  • George IV & Jeffry Wyatville (19th century): Modernized the castle’s exterior and interiors, adding new towers and battlements, expanding state rooms, and redecorating in lavish French-inspired styles.
  • Modern restorations (1992 onwards): Careful rebuilding after the 1992 fire preserved both medieval fortifications and elegant interiors.

Stone by stone, Windsor Castle has evolved through centuries of building, rebuilding, and reimagining, transforming from a royal fortress into the iconic attraction it is today.

Even without daily residents, the castle remains a vibrant ceremonial and State venue. It hosts official events, welcomes distinguished guests, and plays a central role in royal ceremonies.
