Karahan Tepe's T-shaped pillars echo G�bekli Tepe while carrying unique reliefs of blades and animals.

Its stratigraphy places it in the same early Neolithic orbit yet with distinct iconography.

Contested: its social role relative to G�bekli Tepe still needs new OSL sequences to chart the join.

The Guardhouse at Machu Picchu crowns the sun gate, framing the valley with a trapezoidal window.
