Glass coach
The Glass coach is one of the principal State carriages of the British monarch. Built by Peters & Sons of London in 1881, it had originally been designed as a Sheriff's coach, but was purchased by the Crown in time for the Coronation of George V in 1911.
It is used each year on various State occasions, but has most famously been employed at Royal Weddings, either to convey the bride-to-be to the Church before the service, or to transport the newlywed Bride and Groom from Church after the service. Since 2012, it has been used to convey The Queen and the Duke of Edinburgh to and from Horse Guards Parade for Trooping the Colour.
The Glass Coach is driven by a coachman and may be pulled by either two or four horses. When not in use it is maintained at the Royal Mews in London.
More broadly, the term 'glass coach' may be used to describe any coach which is predominantly glazed rather than enclosed.
