Where is logo module position?

In demo template there is a module position named "logo" as I attach, but I can´t see that module position in my template.

Thanks

in my case only I have replaced the default logo image: logo.png

in:

../images/style1/logo.png

or

../images/style2/logo.png

or

../images/style3/logo.png

Thanks a lot vsds

I know how to change image logo, the problem is I need that position for some HTML, not only an image. I though I was able to use that position for custom html module
