Non-Euclidean Architecture
Spatial Anomaly
Structures whose angles and connections violate three-dimensional intuition, characteristic of R'lyeh and Elder Thing construction - and of perception itself under attack.
The geometry of the dream-place he saw was abnormal, non-Euclidean, and loathsomely redolent of spheres and dimensions apart from ours.

Overview
Non-Euclidean architecture is not a style. It is a wound in space left by builders who worked in dimensions humans cannot consciously navigate - Great Old Ones, Elder Things, and powers whose names are worse. R'lyeh is the exemplar: a city where corridors lengthen when pursued, where corners open onto sky that is not sky, where the ground tilts when not observed.
The horror is not ugliness. It is wrongness - the nervous system's recognition that the environment was not made for human bodies or human minds.
Description
Observers report nausea independent of physical instability; headaches that localize behind the eyes; compulsion to draw angles that should not close; and the conviction that something moved in the corner when nothing was visible. Architects who study photographs of R'lyeh or Antarctic ruins have suffered professional breakdowns without visiting the sites.
The Elder Things built with tools and slave labour; their geometry is alien but comprehensible in fresco. R'lyeh's geometry seems to shift with the dream-state of its master - suggesting that space itself may be negotiable for those who dream at cosmic scale.
Historical Record
Johansen's account (1925) is primary for R'lyeh. Dyer's team documented Elder Thing construction in Antarctica - five-pointed symmetry, barrel-vaulted chambers, tunnels that obeyed consistent if non-human rules. Pickman's underground studio in Boston reproduced Dreamlands angles without having travelled there, suggesting contagious transmission through vision alone.
The archive prohibits unauthorized publication of uncorrected architectural surveys.
Archive Notes
Do not attempt to build models for 'educational purposes.' Personnel who dream of five-pointed floor plans are to be screened. If a room in an Arkham boarding house seems larger inside than outside, evacuate and report. Non-Euclidean architecture is often the first symptom that a place has become a door.
