Monaco Bay Weyr was originally established as "Eastern Weyr" and was the second weyr established in the Southern Continent, after the previous seven Weyrs became overcrowded during the Ninth Pass. It was originally made up of just weyrlings and older dragons. As most of the Southern Continent wasn't occupied at the time of its establishment, more experienced riders weren't needed to combat Thread.

Monaco Bay Weyr would be one of the worst victims of the Fireball Flood caused when a meteor impacted in the sea and caused a Tsunami.

Monaco Bay Weyr was soon rebuilt, though it would take longer for the land itself to recover.
