The Secret Church Windows For Viewing Altars

Medieval churches often featured hidden tunnels in walls called hagioscopes. These clever openings allowed worshippers sitting in side chapels to see the high altar clearly, even if they were physically separated from the main service.

You might have heard them called leper windows, but that is actually a nineteenth-century myth. Historians now believe these squinting windows were purely architectural solutions to help people follow the liturgy from cramped corners. Because these walls blocked the line of sight, builders carved these narrow, angled channels to keep everyone connected to the ritual. It is a fascinating example of how medieval design adapted to the constraints of complex church layouts.
