The palace complex consists of a number of residential villas, a smoking hall, a wine cellar, a power station, a monastery, a holy spring, a chapel and many other buildings, as well as most notably a park that is today a state-run botanical garden.

Balkan and Ottoman Turkish motifs were used in the construction of the palace that was carried out by Italian architects Augustino and Americo, while a florist was hired from Switzerland to arrange the park.

The main building's extravagant minaret coexists with a Christian chapel, perfectly illustrating the queen's Baháʼí Faith beliefs.

In 1940, after the reincorporation of Southern Dobruja in Bulgaria with the Treaty of Craiova, the Balchik Botanical Garden was established at the place of the palace's park.

One of the garden's main attractions is the collection of large-sized cactus species arranged outdoors on 1,000 square metres (11,000 sq ft), the second of its kind in Europe after the one in Monaco.
