The Lancken-Granitz dolmens are a group of seven megalith tombs in the Lancken-Granitz municipality on Rügen. Erected during the middle Neolithic, when they were used by the Funnelbeaker culture, at least some were in use until the early Bronze Age. Three of them are encircled by solitary rocks forming either rectangles or a stone circle, one has a solitary 'guardian stone' on its eastern side.
The dolmens were constructed from glacial erratic boulders and red sandstone. In part subdivided into up to four compartments as common for the region, one dolmen showed a subdivision into six such compartments, which is an unusually high number. When the tombs were archaeologically assessed in 1969, Stone and Bronze Age funerary goods were retrieved, including flint hatches, stone axes, amber pearls, bronze needles and necklaces as well as an abundance of arrowheads and pottery.
The dolmens are part of a series built between 3,500 and 3,200 BC, during the Neolithic. As of 2001, about 400 of those are preserved in Mecklenburg-Vorpommern, 55 of which are located on the isle of Rügen. Initially their number had been much larger, but many were destroyed when their boulders were used for church, housing and street construction since the Middle Ages. In the 20th century, local teacher Friedrich-Wilhelm Furthmann and his wife preserved the dolmens in the Lancken-Granitz and Burtevitz area, before they were excavated by archaeologist Ewald Schuldt in 1969 and immediately thereafter restored for touristic use. This was part of a series of 106 excavations conducted by Schuldt's team on megalith sites in present-day Mecklenburg-Vorpommern between 1964 and 1972.
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.
