Dolmen Arca da Piosa
This is one of the mythical dolmens of Galicia. It was known to archaeologists in the 19th century and was studied by the Leisners in 1933.
Located in a large eucalyptus plantation in the parish of Muíño (Zas), the dolmen is in a good state of repair. Four of the five original orthostats are still standing in the polygonal chamber as is a short corridor, of which only a small section is visible, and also the slabs of the roof of the chamber and corridor.
The poet Eduardo Pondal placed this as the tomb of the Celtic warrior Brandomil.
