The Dobrich Province was part of
Bulgaria since 1908, when the country
achieved full independence from the collapsing Ottoman Empire. However, five years later, it was taken over by
Romania in the aftermath of the
Second Balkan War, which Bulgaria lost, thus placing Balchik ten kilometers north of the new border between the two kingdoms, in the
Caliacra County.In 1921, Queen Marie visited Balchik and instantly developed a strong affinity for the area, saying that she "couldn't imagine such a place only in places like
Italy". Romanian noble families were already having summer residences in the area, giving even more reason for a royal residence to be built. Construction began three years later and the complex was completely finished in 1937, the year Queen Marie passed away. Over time, she spent most of her time in the Quiet Nest, the palace proper, which was the first building to be built. In 1940, the region
was ceded back to Bulgaria as a result of the Craiova Treaty, Romania technically still retaining its rights over it by continuing paying taxes for it until 1948. The building became an official property of the Bulgarian state in 1970, when Bulgaria and Romania signed a final agreement regarding the legal status of the palace. Ever since, it was under the full jurisdiction of the
Ministry of Culture of Bulgaria.[https://dvoreca.com/en/kralitsa-mariya.html ==Architectural complex and botanical garden==
