Anta de Arca

Anta/Dolmen - Neolithic (889)
This monument is also known as Pedra da Arca/Anta do Espírito Santo d'Arca/Pedra dos Mouros. It is located on the western slope of the Serra do Caramulo, near Arca, in a place called Paranho de Arca (Arca and Varzielas/ Oliveira de Frades/Viseu). The monument is located in a rural area amidst pine trees and eucalyptus plantations, standing out for being isolated in flat land and free of vegetation. Currently, only the monument's chamber is visible, composed of seven orthostats (from which only three remain whole) that support the capstone. The remaining orthostats are broken slightly above ground level. The chamber is 4.50m long, 3.75m wide and 2.65m tall, with its rectangular capstone having 4.20m long and 3.20m wide. Descriptions from the monument dating from the 18th century are similar to what is observable today, emphasising its landscape prominence, which was influential in the naming of nearby settlements.


Free access. It is integrated in the PR4 walking route - Rota dos Caminhos com Alma.

Good practices when visiting archaeological sites

To visit an archaeological site is to connect with our origins, to understand our path and evolution as a species integrated in the environment, and to respect and safeguard our heritage so that future generations can also visit and enjoy it.

Walking the paths and enjoying the structures and archaeological pieces that survived over time, fosters the understanding of what is different, but also of what is common among different populations: basically, what identifies us as Homo Sapiens.

More than just vestiges and ruins of the past, archaeological sites showcase our capacity for creative thought, adaptation, interconnection, comprehension and resilience. Without these traits we would not have been successful as cultural beings participating in an ongoing evolutionary process. These sites also allow to consider choices made in the past thus contributing for decisions in the present to be made with greater awareness and knowledge.

Archaeological sites are unique and irreplaceable. These sites are fragile resources vulnerable to changes driven by human development. The information they keep, if destroyed, can never be recovered again.

As such, the Directorate-General for Cultural Heritage (DGPC) invites all visitors to enjoy the beauty and authenticity of these sites, while helping to preserve them for future generations by adopting the following set of good practices:

  • Respect all signs; 
  • Do not try to access fenced areas; 
  • Do not climb, sit or walk on archaeological structures and remains; 
  • Respect areas where archaeological excavations are being carried out, not disturbing them; 
  • Do not collect materials or sediments;
  • Do not write or make graffiti on archaeological structures; 
  • Put the garbage in appropriate containers. If none exist, take the garbage with you until you find a suitable container; 
  • Leave the archaeological site as you found it; 
  • Do not drive bicycles or motor vehicles over archaeological sites; 
  • Respect and protect the plants and animals that live in the areas surrounding archaeological sites;
  • Report signs of vandalism or destruction to DGPC or Regional Directorates of Culture (DRC);
  • Share the visiting experience and the archaeological sites, as a way of raising awareness to their preservation and making them better known;
  • Do not buy archaeological materials and report to public security authorities, DGPC or DRC, if you suspect that archaeological materials may be for sale.
