Several monarchs have used golden coaches.
These horse-drawn coaches were made of wood and covered with gold leaf, a solid golden coach would be very expensive and so heavy that it would be a practical impossibility.
Although a gilded coach with or without painted panels was a sign of high social and governmental status, the position of the occupants of the coach determines the number of horses that draw the vehicle.
A prince of the blood royal uses six horses, a nobleman four.
Several coaches of former monarchies are stored or exhibited in European or Asian museums.
