King Manuel I built the Jerónimos Monastery from 1501 using a 5% tax on spices from the India trade — pepper, cinnamon, nutmeg money. Vasco da Gama prayed here the night before his 1497 India voyage and is buried here. The architectural style is Manueline — maritime symbolism carved in limestone: twisted ropes, coral branches, anchors, armillary spheres, sea monsters, knotted cables. Stand at the south portal (Rua de Belém entrance) and find three things in the stone: twisted ropes forming column shafts, coral branches from Mediterranean trade routes, and the armillary sphere (Manuel I's emblem). The Phoenician irony: the monastery celebrates Portuguese "discovery" of sea routes from this exact spot — the Tagus mouth — 2,800 years after Phoenicians sailed from here first.
🔄 BACKUP: If you want to go inside (€21), the two-story cloisters are worth every euro. But the exterior reading alone is free and takes 30 minutes of pure architectural storytelling.
