Cathedral of the Sea (Season 1)

Cathedral of the Sea (La catedral del mar, 2018) is a Spanish historical drama you can watch online on iFILM. Director Jordi Frades adapts Ildefonso Falcones' international bestseller: fourteenth-century Barcelona is booming, and in the fishermen's district of La Ribera, ordinary citizens are raising the Gothic church of Santa María del Mar stone by stone — no royal patronage, no noble money.

At the center is Arnau Estanyol, a serf who escapes his lord's cruelty and reinvents himself in the city. Aitor Luna plays a man who climbs from stone-carrier to merchant, navigating Inquisition witch hunts, feudal revenge and the complicated loyalties of a medieval port. The series runs eight episodes, giving Falcones' dense family saga room to breathe.

For viewers who like period drama built around real architecture and real social upheaval, this is a patient, richly detailed watch. Stream Cathedral of the Sea (2018) online on iFILM.
