Kadriorg Park was established by Peter the Great in 1718 with the construction of Kadriorg Palace and the elegant Flower Garden.

The palace was designed by the Italian architect Nicola Michetti, and its ornate main hall is one of the most exquisite examples of Baroque architecture, both in Estonia and in northern Europe. Most of the Russian rulers visited their imperial summer residence in Kadriorg.

The palace served as the main building of the Art Museum of Estonia in the 1920s, and again in 1946–1991.

In the 1930s, it was the residence of the Head of State of the Republic of Estonia.

In 2000, the palace re-opened as the Kadriorg Art Museum, which displays the largest collection of old Western European and Russian art in Estonia.
