Amisos Hill, or Baruthane Hill, formerly known as the site of the 3rd century BC and discovered on 28 November 1995. The burial chambers in the tumuli were discovered and robbed by treasure hunters before being taken under protection. For this reason, some parts of the grave structures are damaged.
During the excavations carried out in 2004-2005, it was determined that the tumulus belonged to the Hellenistic period and it was found to be a burial structure that is thought to belong to one of the senior management families of the Pontus Kingdom. A number of burials called the Amisos Treasure were also found during the rescue excavations in the burial chambers, and these finds are now on display at the Samsun Archeology and Ethnography Museum.
After the works completed in 2008, the tumuli rearranged to serve tourism were named Amisos Hill and the tomb rooms were opened to visitors.
The northern tumulus, which consists of three consecutive grave chambers located under the hill, which is 8 meters high and 3 meters in diameter, was formed by digging the conglomerate and extends in the east-west direction. The walls of the tumulus, which is 18 meters long, 2.25 meters wide and 2.5 meters high, are decorated with false columns and are not plastered.
The southern tumulus consists of a two-room burial structure under the masonry hill, 15 meters high and 40 meters in diameter. It was formed by carving the conglomerate layer, as in the northern tumulus, and again extends in the east-west direction. The walls under the tumulus, which is 6 meters in length, 2.5 meters in width and 3 meters in height, are covered with 3 meters thick cream-colored plaster.
Horizontal lines were drawn to the walls of the front room in the tumulus and painted in dark blue. On the upper side of this dummy stone weave, two horizontal stripes were engraved with red paint. There are niches painted with yellow paint on the upper, right and left of the door opening to the back room.
There is a kline in front of the western wall in the back chamber of the tumulus. The front of the Kline is decorated with red and black colors. The walls of the room are decorated with red paint and horizontal stripes.
