Located in Red 05 and home to many open bars, kiosks, cart vendors and shops, the name comes from the Mexican word that has come to mean "great marketplace" or "central plaza", though the literal meaning is closer to "base" or "plinth". More than once the Zócalo had to be shut down due to public riots; first in 2259 during the Centauri bombing of Narn, in 2260 following the Earth Alliance declaration of martial law and again in 2261 during the incident with the Thirdspace artifact.
