The Mosque-Cathedral of Cordoba, also known as the Mezquita-Catedral de Cordoba, is a former mosque located in the Andalusian city of Cordoba, Spain. It was built in the 8th century during the Muslim rule in the Iberian Peninsula, and later converted into a cathedral in the 13th century after the Christian reconquest of the city.

The mosque is considered one of the most significant examples of Moorish architecture, with its horseshoe arches, ornate stone carvings, and lush courtyards. The most famous feature of the mosque is the forest of red and white striped arches, which create a stunning display of light and shadow.

In the 16th century, a Gothic-style nave was added to the mosque, which divides the space into two parts: the original Moorish part and the Renaissance-style section. The cathedral also contains a beautiful sacristy, a choir, and a cloister.

Today, the Mosque-Cathedral of Cordoba is a popular tourist attraction, drawing visitors from all over the world to admire its unique blend of architectural styles and rich history. It was declared a World Heritage Site by UNESCO in 1984.
