i enjoyed Februarys challenge so much I though I would give march a go too.
this is one of 3 lions, I think at the tower. it is to remember that in the 1200's there were lions at the Tower. they were given as a gift to the then king. for many years after that there was a menagerie there too. Eventually that was removed to what is now London Zoo. i have added link which i hope works. http://www.hrp.org.uk/TowerofLondon/Stories/Palacehighlights/RoyalBeasts/Menageriehistory
