Megalithic monuments consisting of two menhirs situated relatively close to each other. It is a monolith carved from a block of greywacke, dark gray in color, with a brown patinated surface. It has a star-like appearance, an ellipsoidal cross-section, and measures a little over three meters in height, making it the largest example of greywacke known to date in Portugal. Everything indicates that these menhirs were built in the second half of the fourth millennium BC. The site is surrounded by a net, so it can only be visited from the outside.
