Помогите пожалуйста написать текст про 1 мистическое место на земле прошу

Hello, today Im going to tell you about Newgrange. This is the oldest building in Ireland, this was мейд of priming, rock, clay approximately in 3100 BC. There is a quite long hallway leading to a ward inside the building. The most probably the hallway was used as a grave. One of characteristics of Newgrange is still waterproof. Not a single drop can be leaked inside. Other epic thing of this building is the entrance of a grave is located in this way: when winter comes, rays of sun fall down in the middle of room lighting everything around.
