Terminalia was the last day of the year in the Roman calendar; our system has this as February 23rd.
It was the custom to walks the walls of a settlement on this day, and visit its terminii: this custom is re-enacted, often by psychogeographers, in many places today.
Terminalia was celebrated in Aberystwyth in 2017 by a select group, and will be again in 2018. While the walls are no longer visible, their route is easy to trace. The town map is very clear to this day, and various historical sources confirm the course as:
