Key facts

• The Arco de Santa Catalina and Calle del Arco: the single most photographed monument in Central America — a yellow Baroque arch built in the 17th century by the Convent of Santa Catalina to allow the nuns of the enclosed order to cross Calle del Arco without setting foot in a public street (the arch connects the main convent building to an annexe across the road); the clock on the arch was added in the 19th century; the view through and beyond the arch, looking south to the perfect cone of Volcán de Agua (3,760 m) on the horizon, is the image that defines Antigua in every travel photograph; Calle del Arco itself (renamed 5a Calle Poniente) is a single cobblestoned block flanked by the ruins and intact buildings of former religious institutions
• The Cathedral of San José: one of the most important Baroque religious complexes in the Americas — built 1543, expanded and enriched over two centuries; the 1773 earthquake collapsed most of the nave and the lateral chapels; the ruins of the main church body were not demolished but left as ruins in the atrium; the surviving north-west chapel was repaired and continues to function as the active Cathedral of Antigua; the combined monument (active chapel + Baroque ruin + intact atrium) is unique in the Americas; the crypt below the ruin is the burial place of Pedro de Alvarado (the conquistador of Guatemala) and Bernal Díaz del Castillo (the chronicler of the Conquest of Mexico, author of True History of the Conquest of New Spain)
• The Ruins of La Merced Church: the most spectacular Baroque ruin in Antigua — a 17th-century Mercedarian church whose elaborate white-plaster façade (covered in the “cauliflower” Baroque stucco ornamentation typical of Central American colonial architecture) was reinforced and survives intact, while the earthquake-destroyed nave and cloister behind it have been stabilised as garden ruins; the cloister fountain (the “pila”, 3 metres in diameter) is the largest colonial fountain in Central America; the church is still active; the combination of the intact Baroque façade, the open-sky ruined nave, and the garden cloister makes La Merced the most photogenic single monument in Antigua
• Volcán de Agua and the volcanic setting: Antigua is surrounded by three large volcanoes: Volcán de Agua (3,760 m, dormant but visually dominant — a perfect cone framing the south end of every north–south street in the city), Volcán de Fuego (“Volcano of Fire,” 3,763 m, actively erupting with small lava flows since 1524 — visible at night from Antigua as an orange glow on the horizon), and Volcán Acatenango (3,976 m, dormant); the volcanic setting is not merely scenic — it explains both the earthquakes that damaged the colonial city and the extreme fertility of the surrounding valley (the Guatemala highlands produce high-altitude Arabica coffee widely considered the finest in Central America)
• Semana Santa (Holy Week) processions: Antigua’s Holy Week processions are the largest and most elaborate Catholic processions in the world outside of Spain; the alfombras (carpets) of coloured sawdust, flowers, fruit, and vegetables laid on the cobblestones for the procession route the night before the procession and trampled by the procession itself are made by neighbourhood volunteer groups with designs of extraordinary complexity; the purple-robed Roman soldiers (Cucuruchos) carrying the 3-tonne floats (andas) that bear sculptures of Christ and the Virgin are the defining image; the procession routes are lined shoulder to shoulder with several hundred thousand spectators; the largest processions (Viernes Santo, Good Friday) take place over 12–18 hours
