Queen Saint Isabel and the Legend of Jans
Among several passengers, Amieira barge may have transported the dead body of the Infanta from Aragão who got married with King Dinis,  after her death being canonized and known as Queen Saint Isabel. After her dead in Estremoz and being buried in Coimbra, she was conducted through the path starting in Amieira and finishing at the Tagus margin, wearing a dress made of linen weaved by the Jans, name given to the invisible women who weaved very thin linen and with no knots.  A legend from this region – Legend of Jans - says that when wishing to have a piece of tissue weaved by those fairies, one should leave the linen at night together with a wheat flour cake baking in the fireplace. After finishing their work the fairies disappear mysteriously taking away with them such delicacy.

It is in these lands of North Alentejo, in Barca d'Amieira, which is Herdade of Jans on the banks of an unknown Tagus, quite different from what we see flowing into the broad estuary that bathes Lisbon.
