Inca Architecture
Also known as Inka architecture, Andean dry-stone architecture
An Andean tradition defined by extraordinary mortarless ashlar masonry — stones cut so tightly that no blade can pass between them — integrated with mountain terrain through terracing, trapezoidal openings, and battered walls. Its emblem is Machu Picchu.

About the style
Inca architecture is the monumental tradition of Tawantinsuyu, the largest empire of the pre-Columbian Americas, raised across the Andes in roughly the century before the Spanish arrival in 1533. Unlike the Mesoamerican civilizations, the Inca built almost no true pyramids; their genius lay in stone craft and in fitting structures to steep mountain landscapes. Master masons shaped granite and andesite blocks — some weighing many tons — into polygonal or coursed ashlar that interlocks without mortar, a technique so precise and seismically resilient that walls at Cusco, Sacsayhuamán, and Coricancha still stand after centuries of earthquakes. Buildings share a restrained, repeating vocabulary: inward-leaning (battered) walls, trapezoidal doorways, windows, and niches that taper toward the top, and single-room rectangular structures (kancha compounds) roofed in thatch. The Inca reshaped whole mountainsides with agricultural terraces (andenes), retaining walls, water channels, and staircases, and bound the empire with an immense road network. Machu Picchu, a royal estate of the emperor Pachacuti perched on a ridge above the Urubamba, exemplifies the synthesis — finely dressed masonry, terraced agriculture, and astronomical features all woven into the contours of the sacred landscape.

Clusters of roofless rectangular kancha-type structures of mortarless fitted stone form the residential and ceremonial core of the estate.
Stepped retaining-wall terraces (andenes) stabilized the slope, managed drainage, and created farmable land on near-vertical terrain.

- Parallel / cross-current
Parallel / cross-current Maya Architecture — a parallel pre-Columbian American tradition — fitted dry stone and terracing rather than the Maya stuccoed pyramid-temple
Parallel / cross-current Aztec (Mexica) Architecture — contemporaneous parallel tradition; Andean dry-stone masonry contrasts sharply with the Mesoamerican stepped pyramid
Maya Architecture parallel / cross-current Inca Architecture — a parallel pre-Columbian American monumental tradition — Inca worked in dry stone, without the Maya pyramid-temple or corbel vault
