The Location Pages web part is a pre-configured In Focus web part showing all the Location Pages in Atlas that the user has access to view.
Each tile shows the title, image and created date for the page. Users can go to a specific page by clicking the title or image, and page through the Location Pages using the arrows at the top right.
From Atlas 2.3 onwards you can click the ellipsis (...) in the bottom right to see additional options:
Adding Location Pages
Location Pages are created via the Add It wizard. You can follow the steps to create them here: Add a Location Page

You can customise the layout and query of a Location Pages web part by editing the page, then editing the web part and modifying the configuration options. All the configuration options for In Focus web parts are described in the linked article: Configuration for In Focus web parts
