The Balchik Palace was constructed between 1926 and 1937, during the Romanian control of the region, for the needs of Queen Marie of Romania. 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.
Marie of Romania, the wife of Ferdinand I of Romania, visited Balchik in 1921 and liked the location of the summer residence, ordering the vineyards, gardens and water mills of local citizens to be bought so a palace could be constructed at their place. 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.
Today many of the former royal villas and other buildings of the complex are reorganized inside and used to accommodate tourists. Some of the older Bulgarian water mills have also been preserved and reconstructed as restaurants or tourist villas.
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. It has an area of 65,000 square metres and accommodates 2000 plant species belonging to 85 families and 200 genera. One of the garden's main attractions is the collection of large-sized cactus species arranged outdoors on 1,000 square metres, the second of its kind in Europe after the one in Monaco. Other notable species include the Metasequoia, the Para rubber tree and the Ginkgo.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
