Changsin-dong's quarry cliff is often introduced as a scenic photo spot.
The history beyond the view
Seeing this cliff only as a view misses why the homes packed below it took that shape. Seeing the cliff and the housing below it together is how to read this scenery accurately.
A scene where development and settlement overlay
Seoul's trace of quarrying stone during modernization (the cliff) and the history of people who settled on that spot (the housing) overlay in a single scene. This is not a pretty backdrop but a cross-section showing how the city was made.
