For two years after the fall of Tenochtitlan in 1521, Coyoacán served as the seat of government for New Spain. Hernán Cortés ruled from its low stone houses while the island city across the lake was cleared and rebuilt. The borough never lost the village scale it held then. Coyoacán Bike Tour tours still cross a street grid drawn before 1530, where walls of volcanic tezontle meet lanes too narrow for two carriages to pass. The Nahuatl name is commonly read as the place of coyotes, an etymology the bronze pair in the Fuente de los Coyotes repeats for everyone crossing Jardín Centenario. The Parroquia de San Juan Bautista anchors Plaza Hidalgo. Dominican friars raised its first fabric in the sixteenth century, and the atrium still keeps the proportions of a conventual courtyard. Two streets east stands the Capilla de la Conchita, counted among the earliest Christian chapels built on the American mainland, its carved stone portal weathered to the colour of ash. South of the plaza, the former convent of Churubusco marks 20 August 1847, when Mexican troops under Pedro María Anaya held the walls against the invading United States army until their ammunition ran out. The borough's second life belongs to the twentieth century. Frida Kahlo was born in 1907 in the cobalt house on Calle Londres, painted there, and died there in 1954; it opened as a museum four years later. Diego Rivera kept a studio nearby. Leon Trotsky spent his last years behind the brick parapets on Avenida Viena and was killed in that study in August 1940. Tours en bicicleta por Coyoacán thread these addresses in minutes rather than hours, which is why the quarter reads as one of the few Mexico City landmarks best understood from a saddle. The building stock rewards unhurried looking. Facades run ochre, oxblood and indigo, broken by wooden zaguán doors wide enough for a horse and iron rejas set with bougainvillea. Market halls replaced the colonial tianguis in the 1950s, and the Mercado de Coyoacán still trades in tostadas, mole paste and cut flowers under a vaulted roof. Viveros de Coyoacán, the nursery Miguel Ángel de Quevedo gave to the nation in 1907 and the government declared a national park in 1938, supplies nearly forty hectares of eucalyptus and ash along the old course of the Río Magdalena. Together the colonial plazas, the artists' houses and these cycling routes through Coyoacán's cobblestones form a single argument. A Coyoacán Bike Tour tour makes that argument plainly: Mexico City once lived at the scale of a village, and one village kept the proof.
