Ty Newydd’s tomb was erected during the Neolithic period (4000-2000 BC) by an early-agricultural, organized community. Its building was associated with the transition from gathering and hunting to a more settled life, which influenced the development of a sense of territoriality and rights to inheritance, and thus the desire to pay tribute to ancestors. Probably in the Bronze Age tomb was used again by the population of the Beaker Culture, which fragments of ceramics were found during archaeological research.
The burial chamber was built of four vertically arranged stones that supported a large capstone acting as a ceiling. It is 4 meters long and 1.2 to 1.8 meters thick. Now it is slightly crooked and that’s why it is supported by only three of four stones. The area of the chamber is marked by charcoal from the hearth at the eastern end, where it is assumed that there was a second chamber or passage. The entrance to the chamber was on the north-eastern side. In it there were ceramics from the Bronze Age. Originally, the whole tomb was covered with an artificial mound of earth or stones (cairn) with a diameter of about 32 meters.
