A nice little stop with the pooch and I both getting an ice-cream, plenty of seating outside in a big garden right next to the waterfall

Here in Holywell, one discovers the origins of a saint who is popular not only in Wales: Saint Winifred (actually "Gwenfrewi," other name variations include Winefrieda, Wenefrida, Winfrida, Wenefreda, Guenfrida, Guenvreda, Guenwera). Her name translates as "the friend of peace" or "the white friend of peace." The search for her life and death (as a martyr) takes us back in time to the first half of the seventh century. Saint Winifred's feast day in the calendar of saints is November 3rd. The pilgrimage tradition to Holywell is considered the oldest in Great Britain, but her remains are no longer here; they were transferred to Shrewsbury in the 12th century.

Dechrau a Diwed (Welsh for ‘beginning and end’) is a statue that marks the northern end of the Offa’s Dyke National Trail. Dubbed the ‘Polo Mint’ by locals, the design was inspired by King Offa and the trail, which finishes in Prestatyn. It was unveiled in 2013. Of course, if you have just completed the trail, the real finish line is a boot-less paddle in the sea.
