Show parent page

What I’m looking for is a way to show the Parent Page of a child page. I have found several ways posted of how to just show the sub pages of a selected page but not the other way around.

I am using WP as a CMS so for istance I have:

Project
-Support
-Download
-Contact

When I’m on the “Project Page” I have it set up so that in the sidebar all I see is the subpages for “Project”. Now what I want is for when I’m browsing “Support” for example, is to have “Project” listed in the header or the sidebar.
