Our big dream
Espacio Arcoíris · Fundación Acaye

A place where children can go on being children

When a child faces cancer, their routine and their whole world change overnight. That is why the Espacio Arcoíris (Rainbow Space) was born: a safe, adapted place full of life where children in treatment can switch off, play, learn and, above all, go on being children.

It will be the first in AndalusiaA day centre designed for children with cancer and their families.

Letter from our President

It all began with Cayetano

Dear friend,

Cayetano, my nephew, was 20 months old when leukaemia took him from us. In the months we spent by his side at the Virgen del Rocío Hospital, we learned how much research is still needed and how much families need.

We could not just stand by. In April 2019, a group of relatives and friends from Dos Hermanas founded ACAYE, which means “A Cayetano” (“For Cayetano”). In 2024 we became a foundation.

Today we fund research, support families and bring games, books and volunteers to the hospital. And we dream of the Espacio Arcoíris: a place where children in treatment can go on being children.

Thank you for standing with us.
