St George's Chapel, Windsor Castle

Highlight • Religious Site

St George's Chapel at Windsor Castle in England, is a chapel designed in the high-medieval 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. Seating approximately 800,[1] it is located in the Lower Ward of the castle.

St. George's castle chapel was established in the 14th century by King Edward III and began extensive enlargement in the late 15th century. It has been the location of many royal ceremonies, weddings and burials. Windsor Castle is a principal residence for Queen Elizabeth II and St. George's Chapel is the planned burial site for the Queen.

The day-to-day running of the Chapel is the responsibility of the Dean and Canons of Windsor who make up the religious College of St George, which is directed by a Chapter of the Dean and four Canons, assisted by a Clerk, Virger (traditional spelling of 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.

October 8, 2025, The White Tower – Royal Armouries Museum

The White Tower was built between 1078 and 1100 by William the Conqueror to impress, subdue, and terrify Londoners, as well as deter foreign invaders. Along with the entire Tower Fortress, the White Tower is a UNESCO World Heritage Site and a Grade II listed building. Each floor is filled with exceptional exhibits that demonstrate how this impressive building and the entire Tower have been used over the centuries.

Like Westminster Abbey, St. George's Chapel is a royal mausoleum. Notables buried there include Henry VIII and Jane Seymour, as well as George V and Queen Mary. St. George's Chapel is a working chapel, with services held daily. Although the chapel is closed to visitors on Sundays, services are held there. The origins of Windsor Castle date back to William the Conqueror, who built a stockade mound around 1070. Work was continued by Henry II, who constructed a round stone tower and three outer walls. Henry III built the western end of the lower court with a chapel on the site of the present Albert Memorial Chapel. In 1348, the chapel was used by Edward IV for the ceremony of the investiture of the Order of the Garter.
