The Santuario de las Apariciones is a modest convent chapel in Pontevedra's old centre with an outsized place in modern Marian devotion. It is associated with Sister Lucia of Fatima, who lived here in the 1920s, and with the Pontevedra apparitions linked to the First Saturdays devotion.
Architecturally it is quieter than Pontevedra's larger churches, so come for context rather than spectacle. The interest is in the contrast between the plain urban building and the intensity of pilgrimage attached to it: a local chapel that became part of the wider Fatima story.
