The lion and the unicorn
Were fighting for the crown
The lion beat the unicorn
All around the town.
Some gave them white bread,
And some gave them brown;
Some gave them plum cake
and drummed them out of town.
This rhyme is well known all over the world mainly due to famous Lewis Carroll and his book "Through the Looking-Glass". But you are not behind the mirror, it's just Moscow. And almost here this heraldic creatures continue their fight, just look at this richly decorated building on Nikolskaya street.
This splendid buildin gpreviously belonged to The Moscow Print Yard, the first publishing house in Russia. It was established in Kitai-gorod at the behest of Ivan the Terrible in 1553. In late 18th – early 19th century, the Print Yard building on Nikolskaya Street were dismantled and replaced with a monumental edifice of the Synodal Publishing House (1811-1815). In the 19th century, the buildings of the publishing house were perceived as a single architectural ensemble with the towers and walls of Kitai-gorod, with the add-ons and alterations by future generation architects. The historic headquarters of the Print Yard now house the Russian State University for the Humanities.
