1. The first Web page, hosted at CERN
On March 12, 1989, Tim Berners-Lee published a document with the sober title of "Information Management: A Proposal." He outlined "the management of general information about accelerators and experiments at CERN" and soon set up the first Web server on a NeXT workstation. Great things have small beginnings, and it's humbling to look at this page and realize that literally every single other Web page has descended from it in some form.
