Megalith
Northern style

Northeast Asian megalithic traditions originated from Gojoseon, which was in modern-day Manchuria and North Korea. This was prominent within the Liao River basin in particular in the early phases. The practice of erecting megalithic burials spread quickly from the Liao River Basin and into the Korean Peninsula, where the structure of megaliths is geographically and chronologically distinct. The earliest megalithic burials are called "northern" or "table-style" because they feature an above-ground burial chamber formed by heavy stone slabs that form a rectangular cist. An oversized capstone is placed over the stone slab burial chamber, giving the appearance of a table-top. These megalithic burials date to the early part of the Mumun pottery period (c. 1500–850 BC) and are distributed, with a few exceptions, north of the Han River. Few northern-style megaliths in North Korea and Manchuria contain grave goods such as Liaoning bronze daggers, prompting some archaeologists to interpret the burials as the graves of chiefs or preeminent individuals. However, whether a result of grave-robbery or intentional mortuary behaviour, most northern megaliths contain no grave goods.
