Galesa was created as part of TV channel S4C's Patagonia Week, held between Sunday 26 July and Saturday 1 August 2015 to mark the first Welsh landing in Patagonia 150 years before.

Galesa is a film about identity and determination that proves the pioneering spirit of the original Welsh settlers still exists within their descendants.

The film was made with one professional actress and members of the Welsh community of Patagonia. It was shot using structured reality techniques over 18 days in April 2015.

The film was made alongside the National Theatre Wales theatre production {150}, which incorporated parts of the film into the theatre performance.
