1 Riyal 2006 Asian Games, Environment

Qatar hosted the 15th Asian Games in December 2006 — the first Gulf state to do so — and issued a commemorative series across multiple themes to mark the occasion. The "Environment" coin was part of that broader set, each piece assigned a distinct subject rather than a single unified design. Doha's infrastructure was substantially rebuilt in the lead-up to the games, with the government spending an estimated $2.8 billion on facilities, much of it constructed on reclaimed coastal land along the Arabian Gulf.
