Edinburgh hosts the Hogmanay street party and torchlight procession central to Scotland's largest New Year's celebration.
Edinburgh's Hogmanay is a multi-day festival rather than a single midnight event. Its program has included the torchlight procession, concerts, a large street party, and a midnight fireworks display viewed against Edinburgh Castle. The exact program and capacity can change from year to year, but the city remains internationally associated with the celebration.
The torchlight procession traditionally leads through central Edinburgh before the main New Year's Eve events. Fire and light connect the modern festival with older winter customs, although today's organized procession is a contemporary public event rather than an unchanged survival from a single ancient ceremony.
Glasgow and other Scottish cities also hold New Year's celebrations, so the question is about the nationally prominent Hogmanay festival, not every Scottish party. Edinburgh Castle is the landmark most commonly seen in images of the city's fireworks.
