Cusco

Cusco was the centre of the Inca empire, its name meaning roughly the navel of the world, and the layout still reflects that ambition. Streets in the centre run straight over Inca foundations, colonial arches balanced on stonework so precise it needs no mortar. The city was reputedly planned in the shape of a puma, with Saqsaywaman as its head, and though that geometry takes some imagination to see today, the sense of deliberate design has never quite left it.

When the Spanish arrived they built directly on top of what they found, raising churches over temples and mansions over palaces. That layering is the whole story of the place: colonial façades with Inca walls beneath, Catholic saints processed through squares that were once ceremonial routes. Little was erased so much as built over, which is why Cusco reads less like a museum and more like a document still being edited.

At around 3,400 metres, the city sits high enough that altitude becomes part of the itinerary, not a footnote to it. Most visitors spend a day or two acclimatising before heading further into the valley, and the pace of the place seems to accommodate that. Markets, workshops and courtyards operate at an unhurried register that has less to do with charm than with the practical reality of thin air.

Cusco today functions chiefly as the gateway to Machu Picchu, and it wears that role without apology, its economy built around travellers passing through. But the city has its own gravity too, a working highland capital with a Quechua-speaking hinterland, agricultural terraces still worked in the surrounding hills, and festivals that predate the conquest by centuries.
