How do you delete a place on Roblox

It is not possible to completely remove a place from Roblox. However, you can reset your place by clicking on "Configure this Place", then clicking reset and selecting "Empty Baseplate". Then, simply click update. Your place will be reset to an empty baseplate.

You can also deactivate a place by clicking on the "Places" near the top of the screen when you are in "My Roblox", and clicking the "Deactivate" link next to the place you want to deactivate.
