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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
