New Windsor was considered to be a market town. This designation meant it was given royal permission to conduct trade. This was confirmed by King Edward I’s charter during the late 13th century. However, Windsor’s first merchant guild had already been established in 1369. The current guildhall was constructed in the late 17th century based on a design by Sir Thomas Fitz. It was subsequently expanded in 1829. The building is famous as the venue of two weddings in 2005: Prince Charles and Camilla Parker Bowles plus the controversial ceremony between Sir Elton John and David Furnish on the day the Civil Partnership Act became legal in the U.K. They were legally married in Windsor in 2014.
