Anta do Alto da Toupeira

Anta do Alto da Toupeira is a megalithic monument located in the municipality of Mêda 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 Anta do Alto da Toupeira was constructed during the Chalcolithic period, around 4,000 to 5,000 years ago. It is one of the largest and most well-preserved dolmens in the region.

The dolmen consists of a large chamber formed by seven vertical stones supporting a massive capstone that weighs more than 20 tons. The chamber is accessed by a long passage formed by four 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 Anta do Alto da Toupeira, 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.
