Orca do Ameal is a Neolithic dolmen located in the countryside of Portugal. It sits by a dirt road and is nearby another Neolithic burial chamber. The dolmen consists of three orthostats acting as support stones for a capstone which still sits upon the support stones. The base of the dolmen consists of a circular burial chamber and the mound that was buried the chamber no longer exists. Multiple kerb stones also surround the site and mark the former edge of the mound.
