The Harhoog is a dolmen, a rectangular megalithic tomb from the Funnelbeaker culture, located near Keitum on the island of Sylt in Schleswig-Holstein, Germany. Discovered in 1925, it was moved to the present site in 1954 when a new airport was developed.
The megalithic Harhoog burial chambers were originally located near the mud-flats between Keitum and Tinnum. The stones were moved to the area near the Tipkenhoog on the coast near Keitum in 1954, when Sylt Airport was under development.
The graves at Harhoog are dated to the Neolithic and belonged to ancient settlements of the island's Funnelbeaker culture, probably around 3000 BC. There were once approximately 600 of them but today only about half of them still exist.
The megalithic tombs are built with large, rough stone slabs (one or more) which are arranged in different patterns. Harhoog dolmen is an extended dolmen, under Ernst Sprockhoff's six-category classification; the other five types are simple dolmen, great dolmen, passage grave, long barrows (without a burial chamber) and cist.
Harhhog was discovered in 1925 during excavations of earth for the construction of the Hindenburgdamm, but was only inspected archaeologically in 1936.
References:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
