You have to be either an Account Owner or a Workspace manager to be able to archive Workspaces in your account.
1. How to Archive a Workspace?
You can archive a Workspace along with all of its belonging boards.
Click the "Workspace Settings" icon of the corresponding Workspace and select "Archive Workspace".
A new box appears with information about the Workspace and the Boards you want to archive (Img.1).
If there any unfinished cards on any of the respective boards that box displays their number too.
You can click the arrow next to the board name to open the board and check those cards.
Important: If you archive a Workspace, all Boards in that workspace will be archived irrespective of whether you are assigned to them or not.
Click the "Archive Workspace" button to perform the action.
