The Great dolmen of Dwasieden is a megalithic site of the Funnelbeaker culture, which was constructed between 3500 and 2800 BC.
The dolmen lies in a roughly northeast-southwest oriented, trapezoidal hunebed about 35 metres long and 12.5 to 7.5 metres wide. Of the 54 kerb stones - including the four guardian stones - 41 have survived. The rectangular, roughly east-west oriented chamber at the wide end of the frame, with its western entrance and porch consists of seven supporting stones, a half stone the height of the uprights and five slabs, on which there are three large (on the chamber) and three small capstones. Only the central capstone of the chamber is missing. One of the four guardian stones at the southwest end, which had already been overturned in the past, has 40 cup marks, one of the kerb stones has three more. The site is a prime example of the porch dolmen (Großdolmen mit Windfang), typical of this region. A two-metre-long porch runs past the support-high half stone to the 4.0 metre long, 1.7 metre wide and 1.4 metre high chamber. The hall consists of red sandstone slabs, annealed flint and a clay floor.
Neither human bones nor cremated remains were found, but it has been established that it was later used by members of the Globular Amphora culture. The artefacts found include 1,777 shards, the largest amount of pottery in a site in Mecklenburg-Western Pomerania. There were also 19 blades, eleven amber beads, eight cups, six crosscutters, six scrapers, five biconical vessels, five bowls, two funnel bowls, a scraper (Schaber), a hammerstone and a narrow chisel.References:
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
