The Dolmen of Carapito I is a megalithic monument located in the municipality of Aguiar da Beira, in the north-central region of Portugal. It is a dolmen, which is a type of prehistoric tomb consisting of two or more vertical stones supporting a horizontal capstone.
The Dolmen of Carapito I was built during the Neolithic period, around 5,000 years ago, and is one of the largest dolmens in Portugal. It is located on a hilltop, and its position and size suggest that it was an important site for the prehistoric community that built it.
The dolmen consists of a large chamber formed by several vertical stones supporting a massive capstone that weighs approximately 17 tons. The chamber is accessed by a long passage formed by two portal stones. The dolmen is surrounded by a circular mound of earth, which was likely used to mark the site and provide support for the stones.
The purpose of the Dolmen of Carapito I, like many other dolmens, is not fully understood. It is believed to have been a tomb, used for the burial of important members of the community. However, it is also possible that it was used for other purposes, such as religious or ceremonial activities.
