Castelo de Alfeizerão

Portugal, Portugal

---

Castelo de Alfeizerão is a ruined medieval fortress in Alfeizerão, Alcobaça municipality, Portugal, with origins possibly tracing to the 8th century Muslim invasion when Arabs may have founded a settlement named "Al-cheizaram," meaning small reedbed, on a hill overlooking the Atlantic coast between Nazaré and Peniche.

Conquered and rebuilt around 1147 by King Afonso Henriques during the Reconquista, the Romanesque castle defended the coastal stretch and local Coutos de Alcobaça lands under Cistercian control until the religious orders' extinction in 1834, after which it passed to private hands and largely vanished.

Today, only scant wall remnants and traces remain in poor condition on a 45-meter hilltop, evoking its role as a modest watchpost amid prehistoric and early medieval layers, with King Manuel I granting the village a new charter and pillory in 1514.
