Easter in Orihuela is renowned not only for its monuments, landscapes, traditions, and Mediterranean light but also for its rich history and artistic qualities.

Built upon the remains of a mosque, this church is dedicated to the city's patron saints, whose martyrdom coincides with the traditional date of the city's reconquest, believed to have occurred on July 17, 1243. The structure is a single-nave Gothic temple, featuring side chapels between buttresses that date back to the 14th and 15th centuries. The presbytery and the side doorway, known as the Anunciación, are designed in Renaissance style. Alongside the nave, the Baroque Communion Chapel can be found. The main facade is adorned with a grand doorway, also in Baroque style, which was crafted by Antonio Villanueva and Cristóbal Sánchez. Particular attention should be given to the Gothic-style bell tower, which is remarkably slender and likely completed in the mid-15th century. The tower features gargoyle-shaped drains in its corners and sculptures of mythical beasts. Additionally, the clock, commissioned by the town council in 1439, is of historical interest.
