Why is hill16 called hill16?

Hill 16 is named after a prominent rise in the landscape of Croke Park, Dublin, which was originally a site for a military fortification during the 19th century. The name "Hill 16" itself references the 16th hill of a series of military positions during World War I. Over time, it became associated with the stadium where Gaelic games are played, and it has since evolved into a symbolic and iconic location for fans, particularly in the context of Irish sports and culture. The hill is also a popular standing area for supporters during matches.
