San Francisco Convent sits just outside the tight maritime centre of Muros and gives the town a deeper historical register. Galicia's tourism office traces the site to an older church and late-medieval Franciscan origins, with later changes after abandonment and reuse.
It is worth adding to a Muros walk if you are interested in the religious landscape behind the harbourfront. The convent is quieter than the town's granite arcades and seafood streets, but it helps explain Muros as more than a pretty riaside stop.
