In the 16th and 17th centuries, many government bodies were situated in the Ivanovskaya Square.
It was the site of the Prikazy, the equivalent of today's Ministries.
Yamskoi Prikaz, one of the offices, handled the delivery of private letters.
At the end of the 1920s and early 1930s, the square was enlarged after the demolition of the Lesser Nicholas Palace and the Ascension Convent.
Today, the square is cobbled like most of the territory of the Kremlin.
