There are two good reasons to visit Viana's 228m, eucalyptus-clad hill, Monte de Santa Luzia. One is the god's-eye view down the coast and up the Lima valley. The other is the Templo do Sagrado Coração de Jesus.

There's an over-the-top Pousada de Portugal (Pousada do Monte de Santa Luzia) up here, too, behind and above the basilica. Behind that is another attraction, the poorly maintained ruins of a Celtiberian citânia from around the 4th century BC, though these remained closed for redevelopment at the time of writing. You can also make the short walk onwards to the summit.

You can get up the mountain by car or taxi (3.5km) or on foot - an often steep, 2km climb only for the fit and/or penitent. The road starts by the hospital, and the steps begin about 200m up the road. An old funicular to the top has been growing rusty from disuse.
