Belem is best reached from central Lisbon by tram 15. The journey takes about 20 minutes and follows the bank of the River Tagus. Both old and new trams operate on this route.
Belem is dominated by the Manueline architecture of the sixteenth century Monastery of St Jerome (Mosteiro dos Jeronimos). The south entrance to the church is exuberantly decorated, as are the vaulted arcades of the cloisters, with a mixture of religious themes and items related to Portugal’s maritime experience at the time of construction.
The nave of the church has spectacular slender octagonal pillars creating the impression that the roof is kept aloft by palms. The church contains the tombs of several Kings including Manuel I, Joao III and the empty tomb of King Sebastiao whose body was never recovered after dying in battle in 1578 trying to conquer Morocco. Each tomb is oddly supported by a pair of elephants!
Close to the rear entrance is the tomb of discoverer Vasco da Gama. His tomb is carved with seafaring instruments as well as religious symbols and artichokes. The discovery that the humble artichoke could be used to prevent scurvy was a major breakthrough in improving the health of intercontinental sailors.
The main attractions of the cloisters (free entry on Sundays) are the richly carved arches and balustrades, which were being cleaned and restored during 2001. The refectory is tiled with azulejos depicting biblical themes. Rooms in the cloister were rather bare. I have no idea though whether that is permanent or just as a result of the restoration in progress.
The famous Pasteis de Belem (custard pastry) can by bought just down the road from the Monastry close to the tram stop.
