The Memorial da Irma Lucia is a small religious museum connected to Sister Lucia, one of the three children of Fatima who later lived as a Carmelite nun in Coimbra. It gives the Fatima story a quieter, more personal setting than the great sanctuary itself.
The visit will mean most to travellers interested in Catholic history or Portuguese pilgrimage culture. It is reflective rather than showy, and it fits naturally with Coimbra's convents, churches, and university-town seriousness.
