On two days a year - the feast day of Saint Martin on 11 November and Candlemas (today) - the positioning of the giant eastern window of Palma Cathedral allows early morning sunlight at dawn to pass through the Cathedral and form a reflection below the smaller western window. The phenomenon, known as "8", occurs around 8 in the morning, the appearance of this "8" being the double rosette of the western window and the reflected eastern window, which is also known as the Gothic eye.

Hundreds of people gathered in the Cathedral this morning to witness the phenomenon and to snap its appearance on cameras and phones.
