The Tinto River is famous for its intense red-colored waters and extreme acidity, caused by the oxidation of iron and sulfide minerals. It is so peculiar that NASA and other space agencies study it as a terrestrial analogue of Mars, as its extreme conditions host microorganisms capable of surviving in very hostile environments. Furthermore, the area has been mined for over 5000 years by Phoenicians, Romans, and other civilizations.

The area is linked to the Iberian Pyrite Belt, where copper and other metal mining was intense from the 19th century onwards. To transport the ore, the British built the Riotinto Railway (1873-1875), which included numerous bridges over the Tinto River and its tributaries. Many of these bridges fell into disuse after the railway line closed in the 20th century and remain today as industrial remnants.

Origin: Built during the Almohad period (12th-13th centuries), as part of Niebla's defensive system. Legend of the name: During the siege by Alfonso X the Wise (1262), the last Muslim king of Niebla, Aben-Mafot, sent a fattened ox out through this gate to create the illusion of abundant provisions and discourage the Christian troops. The stratagem failed, and the city was conquered.

The Puerta del Buey (Ox Gate) is one of the most emblematic entrances to the walled town of Niebla (Huelva), with great historical and architectural value. It is located on Avenida Puerta del Buey, next to the Tinto River, and forms part of the Almohad wall that surrounds the town.

The Parish Church of Santa María de la Purificación, due to its volumetric force and its location in an elevated part of the town, becomes the most representative architectural landmark. Despite being initially located away from the urban center, it is a remarkable example of a Sevillian church, in which the Mudejar and Baroque styles converge, following a very characteristic approach to 18th-century construction practice in the area. Built according to Mudejar principles in its original construction, which appears to date from the 15th century, it would later be practically rebuilt after the damage caused by the 1755 earthquake, conforming to the Baroque guidelines prevailing in the second half of the 17th century. A reconstruction in which Pedro de Silva, Antonio Matías de Figueroa, and José Álvarez participated. Among them, Antonio Matías de Figueroa stands out for the significance of his intervention in the complex. His work on the Manzanilla church can therefore be considered one of the last examples of this family's distinctive style—the so-called triumphal baroque—and one of the first signs of the change of direction demanded by the changing times, in their preference for the primacy of Rococo lines over Baroque masses. The appearance of neoclassical elements (the Gospel nave portal), derived from the presence of José Alvarez (1782–1783) as director of the works, also speaks to the formal evolution of the style toward the last quarter of the century. Finally, the tower (1760-1779) stands out, attributed to Lucas Cintora and Francisco Díaz Pinto, and one of the most beautiful examples in the province. It perfectly fits one of the two characteristic typologies of 18th-century Andalusia, originating from the Giralda in Seville. It forms part of a unique group of towers in Huelva, along with that of the Temple of San Pedro in Huelva and that of the Church of San Juan Bautista (La Palma del Condado), all of which follow a very similar model. This building represents another example of the intense religious construction activity that characterized 18th-century Huelva architecture, motivated by a fortunate combination of economic, demographic, and natural circumstances (earthquakes), and which has come to be known as its Golden Age.

The Plaza de España in La Palma del Condado is an emblematic and central place in this charming town in the province of Huelva. Surrounded by historic buildings and with a vibrant atmosphere, it is a popular meeting point for both locals and visitors. In this square, you can find the Parish Church of San Juan Bautista, one of the most representative churches of the 18th century Sevillian Baroque style. In addition, the square is close to other points of interest such as the Convent of Our Lady of Carmen and the Old Town Hall.
