Pope Francis has returned to a practice he developed during the Year of Mercy: making a Friday afternoon visit to people in need of or deserving special care.

For the visit, he chose the Sant' Alessio-Margherita di Savoia Regional Centre for the Blind in Rome. The centre is home to 37 adults and senior citizens who are blind or severely visually impaired, but the structure also offers specialised classes for 50 children with the same challenges.

"With this visit, the Pope wants to continue the so-called Mercy Friday visits carried out during the Jubilee of Mercy," the Vatican said in a statement.
