You must believe that the city of London is protected by Dragons. In fact, there are 13 Dragons marking the boundary of the city. There used to be a building called the Coal Exchange built in 1849. Adorning the building were 2 seven foot tall Dragons. In the late 1960’s the Coal Exchange was demolished, but the Dragons live on. The 2 Dragons were mounted on plinths on either side of Victoria Embankment to mark the boundary between Westminster and London.
These 2 Dragons served as the model for the city Dragons. Another Dragon was in contention for the honor and can be seen at the site of the original Temple Bar. This lone Dragon is much fiercer than the others.
If you have any doubt as to whether or not you are in London, look to these guardians. Each Dragon faces outward to protect the city. If you are seeing the Dragon’s backside then you are truly inside London.
Why Dragons? The City of London crest has been supported by Dragons since the 17th century. Since the 17th century the City of London crest has been supported by a pair of dragons. It makes sense as the City of London has used the St. George’s Cross and Emblem, in heraldry having animals (real or mythical) as supporters for a crest is quite common. One theory for the choice of dragons for the City is that the since the 14th century the City of London has used St. George’s cross as an emblem and a dragon. Since a Dragon is a key part of the legend of St. George, it makes sense.
