Antelas dolmen
Pinheiro, Portugal
The Anta Pintada de Antelas (Antelas Painted Dolmen), also known as the Dolmen de Antelas or the Dolmen Pintada, is located about 250m. east of the village of Antelas, in the parish of Pinheiro de Lafões, in the municipality of Oliveira de Frades in Portugal's Viseu District. Classified as a National Monument since 1990, this dolmen, or megalithic tomb, is notable for its well-preserved set of paintings and engravings, arguably the best from the Neolithic period in the Iberian Peninsula.
