Hili 10 building is about few steps away from the main entrance of the park. The whole area is well covered with green fences and there's no way that any visitor can enter the area to check out what's inside the grounds. It looks more of a broken circular wall with partitions.
Text written below is the information from Abu Dhabi Authority for Culture and Heritage.
These are the remains of a single building which may have been only the central part of a larger settlement. Only the foundations of the building remain, as the original floors and the upper wall have been eroded away by the time. The types of pottery discovered indicate that the building belonged to one of the bronze age phases (second half of the 3rd millennium BC) and it was reoccupied during the iron age (1st millennium BC). It has a well to serve the occupants in peace and in case it was besieged during the conflict.
Sun dried mud bricks was the main construction material used in the domestic architecture of the 3rd millennium BC in the region. Carefully cut stones were used in the construction of the near by tombs which belong to the same period.
