Indigenous Metalwork, the San Bernabé Vein, and the World's Silver Capital
Set in a deep, winding ravine of the Guanajuato mountain range (known locally as the Sierra of San Gregorio) at an altitude of 2,045 to 2,084 metres (6,709 feet) in the Bajío macroregion of central Mexico, the colonial city of Guanajuato and its surrounding silver mines preserve the urban and industrial fabric of the 18th-century world's leading silver-extraction centre. Long before Spanish arrival, Otomi inhabitants (who called the site Ndänuë), Chichimeca groups, Purépecha traders (who named it kuanhasï juáta, or "frog hill", the source of Guanaxhuata and Guanajuato), and Aztecs (who called it Mo-o-ti, "place of metals", and Paxtitlán) gathered surface gold and minerals across these hills. After Spaniards discovered rich silver and gold outcrops in the 1540s, beginning with the San Bernabé vein at La Luz and the Bocamina de San Ramón mother lode in 1548, Viceroy Don Antonio de Mendoza formally established the Real de Minas de Guanajuato in 1548 around 4 fortifications at Marfil (Santiago), Tepetapa, Santa Ana, and Cerro del Cuarto (Santa Fe, in modern Pastita). Consecrated with its first parish church in 1555 with Preafán de Rivera as mayor and named an alcaldía mayor in 1574, the settlement received its formal royal city title and a Castille coat of arms from Viceroy Fray Payo Enriquez de Rivera in 1679, further honours in 1741, and provincial intendencia status in 1790.
During the 18th century, the surrounding mines, led by La Valenciana (opened in 1774, descending 450 metres, employing 10,000 miners, and supplying two-thirds of global silver output at its peak and 30% over 250 years, rivalling colonial mining centres such as Zacatecas in Mexico, Potosí in Bolivia, and Brazil's Ouro Preto), together with La Cata (1558), Rayas (found in 1550 by Juan Rayas with a 425-metre shaft and the 600-metre Boca del Inferno), Mellado, Guadalupe, and San Luisito, generated immense wealth for noble families such as Antonio de Obregón y Alcocer (Count of Valenciana), José de Sardineta y Legaspi (Marquis of Rayas and Viscount of Sardineta), and the Marquis of San Clemente. Yet stark inequality sparked revolts at the Caja Real (1665) and protests when the Jesuits were expelled in 1767. After Father Miguel Hidalgo y Costilla launched the Grito de Dolores on 15 and 16 September 1810, insurgent forces marched through Callejón Tecolote on 28 September 1810 to besiege Lieutenant Riaño and royalist troops inside the massive Alhóndiga de Granaditas granary (built from 1798 by Durán y Villaseñor and José del Mazo after the 1783 famine). The stalemate broke when the miner Juan José de los Reyes Martínez, known as El Pípila, strapped a flat stone to his back and torched the wooden portal.
Named state capital in 1824, Guanajuato served as Liberal President Benito Juárez's provisional national capital in 1858 at the Casa de Gobierno, endured French occupation from 1863 to 1867 with a visit by Emperor Maximiliano I, and Carlota before General Florencio Antillón recaptured it on 26 January 1868, and saw renewed foreign mining investment in the 1870s under President Porfirio Díaz, who inaugurated the Teatro Juárez (designed by Antonio Rivas Mercado and constructed between 1872 and 1903) with Giuseppe Verdi's Aida and the metallic Hidalgo Market (built by Ernesto Brunel in 1910 over the Gavira bullring). In 1950s Plaza San Roque, Enrique Ruelas Espinosa staged outdoor Entremeses Cervantinos that grew in 1972 into the annual Festival Internacional Cervantino, hosted across 70 October venues including the University of Guanajuato, Teatro Principal, and Cervantes Theater.
Subterranean River Streets, Narrow Alleys, and Churrigueresque Masterpieces
Unlike colonial Mexican cities laid out on a flat checkerboard grid, Guanajuato adapted organically to its steep ravine topography across a 12.25-square-kilometre urban core (population 70,068 within a 1,014-square-kilometre municipality of 194,500 residents across 373 communities in Region I, surrounded by 2,400-metre peaks such as Cerro de la Bufa, Santa Rosa, Chichíndaro, and Sirena, with Cubilete Mountain crowned in 1923 by Nicolás Mariscal Piña and Fidias Elizondo's 20-metre, 250-ton Christ the King Monument). Because catastrophic floods in 1760 and 1780 devastated the valley floor, engineers excavated drainage tunnels such as Túnel La Galereña in the early 1800s and built dams like the mid-18th-century Presa de la Olla (where the Feast of San Juan is celebrated every 24 June). After 1960s dam construction tamed the river, the old underground channels, led by the 3-kilometre Belaunzarán (Miguel Hidalgo) thoroughfare opened to vehicles in 1961 and expanded in the late 1960s and 1990s, were converted into a multi-level subterranean road and pedestrian network with underground junctions and bus stops.
Above ground, Juárez Street links pocket plazas paved in cut stone, including Plaza de la Paz, Jardín de la Unión (landscaped in 1883 with Indian laurels and a bandstand), Plaza de Baratillo (1726, with a fountain from Florence, Italy), Jardín Reforma (1861 market converted into a garden in 1923), Plaza San Fernando, Plaza de los Ángeles, Plaza de Mexiamora, and Plaza del Quijote (marking the 400th anniversary of the 1605 novel), while steep pedestrian stairways and alleys climb the hillsides. Famous lanes include "Sal si puedes", Callejón de la Condesa, and the 168-centimetre-wide Callejón del Beso on Cerro del Gallo, linked to the legend of Doña Carmen and Don Luis. Around Plaza de la Paz stand the pink-and-green sandstone mansions of the Counts of Rul (designed by Francisco Eduardo Tresguerras, where Alexander von Humboldt stayed in 1803, later Palacio de Otero), Count of Gálvez, and Count De los Chico, alongside the Casa Real de Ensaye, Cecilio Luis Long's 1903 Neoclassical Legislative Palace, and the main parish church, the Basílica Colegiata (constructed from 1671 to 1696, elevated to basilica in 1957, housing the 1557 statue of Nuestra Señora de Guanajuato donated by Carlos I, and Felipe II, plus relics of Saint Faustina).
Two sanctuaries are celebrated as masterpieces of Mexican Churrigueresque Baroque architecture in Central and South America: the Jesuit church of La Compañía (Oratorio de San Felipe, built from 1745 or 1746 to 1765 or 1767 by José Joaquín Sardaneta y Legazpi, reclaimed in 1804, crowned with a 3-tiered 19th-century cupola by Vicente Heredia, and housing 180 paintings and an altar by Miguel Cabrera) and the hilltop San Cayetano de la Valenciana Church (1765 to 1788), whose gilded altarpieces and ivory-inlaid pulpit overlook the Valenciana shaft. Next to La Compañía rises the green-stone Neoclassical main building of the University of Guanajuato, founded in 1732 by Josefa Teresa de Busto y Moya (known as the Purísima Concepción Royal College in 1767, Colegio del Estado in 1828, Colegio Nacional in 1867, and a university in 1945 serving 30,000 students), featuring a 113-step staircase above Callejón del Estudiante, Vasco de Quiroga's 16th-century Templo de los Hospitales, and the Alfredo Dugès Natural History Museum.
Walking the Ravine Plazas, Historic Mine Shafts, and Civic Museums
Travellers consulting the UNESCO World Heritage Atlas should explore Guanajuato on foot by riding the funicular behind the Teatro Juárez up to the El Pípila Monument on San Miguel Hill for a panoramic orientation over the ravine, then descending into the historic centre to follow Juárez Street from Jardín de la Unión and the 1780-to-1784 San Diego Church past Plaza de la Paz and the 113 steps of the University of Guanajuato to the Hidalgo Market and the Alhóndiga de Granaditas. Inside the Alhóndiga, which functioned as a state prison from 1864 to 1949 before opening as the INAH regional museum (restored in 2010 for 5.7 million pesos), 14 upper-floor halls, stair murals by José Chávez Morado, Chupícuaro ceramics, and works by Hermeneguildo Bustos and Romualdo García trace regional and independence history.
Art and cultural stops along the valley include the birthplace museum of muralist Diego Rivera (housing 100 early works), the Museo del Pueblo, the Museo Iconográfico del Quijote (founded in 1987 on Manuel Doblado Street with works by Pedro Coronel, Salvador Dalí, and printmaker José Guadalupe Posada), the Olga Costa and José Chávez Morado museum in Pastita, the Gene Byron museum in Marfil (established in 1962 in a former hacienda), and the Tepetapa Mummy Museum, where 59 of 111 naturally mummified bodies exhumed between 1870 and 1958 (beginning with French doctor Remigio Leroy, studied by Dr Eduardo Hicks in 2007, and displayed at the Detroit Science Center in 2009) are exhibited behind glass. A short bus or taxi ride up the Carretera Panorámica reaches the 1765-to-1788 San Cayetano Church and the historic shafts of La Valenciana, Bocamina de San Ramón, La Cata, and Rayas. The alleys are steep.
- Orienting from the El Pípila overlook: Take the cable car behind Teatro Juárez to San Miguel Hill first to see how the pink and green sandstone churches, 113 university steps, and canyon streets fit into the Sierra of Guanajuato valley.
- Pairing underground streets with surface alleys: Walk a section of the subterranean footpaths along the Belaunzarán river tunnel, then emerge at Jardín de la Unión to join an evening student musical callejoneada through Callejón del Beso.
- Visiting the hilltop mining complexes: Dedicate half a day along the northern panoramic ridge to inspect the Churrigueresque stone portal and gilded altars of La Valenciana Church together with the adjacent mine shafts of La Valenciana, Rayas, and San Ramón.
