La cantera, from above — Madrid, 2006–2023

La cantera — “the quarry” — is what Spanish football calls the system that grows its players.

Spain holds both World Cups — the first country ever to hold both at once. It didn't come from nowhere. Since 2006, greater Madrid alone has built or resurfaced at least 257 football pitches, 11-a-side and 5-a-side (detected in 351 chips), found in Spain's national aerial survey (PNOA, IGN España) with LGND's technology.
