The Great Dolmen of Zambujeiro, 13km southwest of Évora, is Europe’s largest dolmen. Under a huge sheet-metal protective shelter in a field of wildflowers and yellow broom, stand seven stones and a ‘closing slab’ that connects the chamber with the corridor. Each is 6m high and together they form a huge chamber around 5m in diameter.
Unfortunately the entrance is blocked and you cannot enter; but you can peer in from the high mound behind. Archaeologists removed the capstone in the 1960s. Most of the site’s relics are in the Museu do Évora.
