The Holy Week is a deeply-rooted religious festivity in the municipality whose origins date back to the 15th century. It has been declared a Festivity of Provincial Tourist Interest, organised by the Junta Central (committee) of the Holy Week.
It begins with the Pregó (opening speech), which is followed by different processions and sacramental acts, among which the following stand out:
- The Washing of the Feet.
- The Rompida de la Hora (breaking of the hour). This has become, the most multitudinous act of Holy Week in Almassora at midnight on Maundy Thursday.
- The sermon of the Descent from the Cross. It has a unique peculiarity in the province of Castelló, the Christ with his articulated arms so that he can be decrucified and then placed in the Holy Sepulchre with his arms folded.
- The procession of the Holy Burial on Good Friday.
- On Easter Sunday the meeting of the images of the Risen Christ and the Virgin.
Then Easter is celebrated, with the traditional nature excursions with friends to eat Easter cake, taking advantage of the longer days. Until a few years ago, it was typical going to eat the Easter cake to Revallaores. Currently, the festivity has moved to the farms and "masets" of the municipality.
