This page uses header template #3 which is made up of two main rows. The top row features two menu locations, each one located either side of the logo, site title, and site description (which are located in the centrally on the page). The bottom row features another menu location.
Don’t forget, header templates are dynamic so you can configure each one to use different menus and widgets. Also, if you don’t define anything to display in a particular row then it isn’t displayed.
This means all rows are optional allowing even more flexibility in how your header looks.
