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.

Built between 527 and 565 AD at the foot of Mount Sinai for Emperor Justinian, this monastery later took its name from St Catherine of Alexandria, whose remains are said to rest here. It’s more fortress than church, with thick stone walls guarding the Church of the Transfiguration, the chapel of the Burning Bush, and a monks-only library packed with ancient manuscripts. Inside, you’ll find mosaics, religious ornaments, and some of the oldest illuminated manuscripts in the world on display. Outside, don’t miss Moses’ Well and the garden with centuries of history. The place is open most mornings but closed on Fridays, Sundays, and Orthodox feast days. Still active today, the monastery holds importance across Christianity, Judaism, and Islam, and continues its Greek Orthodox traditions uninterrupted.

Built in the early 1400s, around the same time as the Forbidden City, the Temple of Heaven was where emperors prayed for good harvests. The vast park contains several ceremonial buildings, the most striking being the Hall of Prayer for Good Harvests with its blue-tiled roof and intricate wooden ceiling. The original hall was destroyed by lightning in 1889 but rebuilt soon after. Other highlights include the Hall of Abstinence, where emperors fasted before rituals, and the Circular Mound Altar — a three-tiered marble platform symbolising heaven itself. Today, the park is as much about everyday life as it is about history: locals gather here in the mornings for tai chi, dancing, and music.

According to tradition, this church was constructed on the site of the former Gothic Parish of Saint Julian after the image of the Virgin Mary was unearthed following the city's recapture from Moorish rule. The building is a Baroque temple designed in the shape of a Latin cross, with a Neoclassical facade displaying the anagram of Our Lady of Monserrate. Inside, the Hallazgo chapel contains a cave where the image of the Virgin Mary is believed to have appeared. Above this site, the old niche is now dedicated to the Cristo de la Buena Muerte. The high altar is home to the niche containing the Virgin of Monserrate, the city's patron saint.
