🇵🇪 Cusco before Machu Picchu: altitude, timing, and choosing a local guide

Cusco was the capital of the Inca Empire — Tawantinsuyu — and the Inca laid it out in the shape of a puma, with the fortress of Sacsayhuamán forming the head. When the Spanish arrived in 1533, they dismantled Inca temples and raised colonial churches directly on the original stone foundations, creating the extraordinary layered architecture that defines the city today. The Plaza de Armas occupies what was once the Inca ceremonial square of Huacaypata, and its flanking Cathedral and Jesuit church of La Compañía rest on Inca walls so precisely fitted that a knife blade cannot slip between the stones. At 3,400 metres above sea level, altitude shapes every part of the Cusco experience. Most visitors arriving from Lima feel breathless within minutes of stepping off the plane, and the conventional wisdom — rest your first day, drink coca-leaf tea, eat lightly — genuinely matters. Once acclimatised, the city reveals itself as both a living museum and a vibrant Andean hub: the San Pedro Market overflows with tropical fruit, fresh cheese, and steaming bowls of quinoa soup, while the cobblestone lanes of the San Blas artisan quarter climb past textile weavers, silversmiths, and a Quechua-speaking population that has carried Inca traditions across five centuries. Cusco matters to Peru far beyond its ruins. Written into the country's constitution as the Historical Capital of Peru, it is the cultural and economic engine of the southern Andes and the gateway through which most travellers reach Machu Picchu and the terraced towns of the Sacred Valley. Its history is still legible in stone: the Inca sun temple of Qorikancha, once sheathed in gold, survives beneath the colonial church of Santo Domingo; the Cathedral holds the Cusco School canvases that fused European religious painting with Andean symbolism; and it was on the Plaza de Armas that Túpac Amaru, the last Inca ruler, was executed in 1572. The result is a UNESCO-listed city where the Inca and Spanish worlds are stacked on the same walls, block by block.
