The Bay House was the Duchess of Harrington's private residence near the city of Landing on Manticore. It would normally have been called "Harrington House", but as that name was already used for Harrington's residence in Harrington Steading on the planet Grayson, it was named the "Bay House" instead, due to its location on Jason Bay's eastern shore, a ten minute aircar ride from the center of downtown Landing.
