The first written record of the Blankenfelde manor dates from 1689 when the owner was Ernst von Medem. The estate changed owners several times and was part of the von Hahnide family from 1840 until 1920. Between 1804 and 1805 the manor belonged to the Russian imperial house of Andreas von Königfelsile. Louis XVIII, King of France, lived in Blankenfelde manor for a while when he was in exile.
The complex structure of the manor dates from the mid 18th century, and the main building erected in 1743 has a 19th-century English-style park. There are currently ideas for the exploration of the estate in the concept of private ownership and tourism. The renovation work of the main building is now underway. Blankenfelde estate flower garden is part of the spring tulbifestivale.
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.
