In the wild, boulder-strewn landscape around Castelo de Vide are dozens of ancient megaliths. The two most impressive are the Anta da Melriça, northwest of town, and the 7m-high Menhir da Meada, around 13km north of town. This is supposedly the tallest menhir in the Iberian Peninsula – a large phallus for keeping the fields fertile and acting as a territory marker (one of the few believed to have done both jobs). The so called Parque Megalítico dos Coureleiros is a collection of five different arrangements.
These megaliths are best accessible by car. Ask for a map from the tourist office.
