United Kingdom: Windsor Castle

Last Tuesday I got five postcards: three from the United Kingdom, one from Andorra and one from Sweden

One of the cards from the United Kingdom shows Windsor Castle. Windsor Castle was originally built in the 11th century by William the Conquerer and since the 12th century it has been used by the reigning monarch making it the longest-occupied palace in Europa. Over the centuries the castle was often enlarged and redesigned.

Stamps:

Thank You very much William!
