got[26] - limestone boulder

The inset plaque reads [In Welsh & English] ---
.
"This boulder is one of many
that fell onto the Marine Drive
on 10th June 1993
As a result of the floods in which
5 inches of rain fell in a 3 hour period
It was not the biggest ! "

IMHO, That must weigh nearly a ton .

Marine Drive circumnavigates the Great Orme headland.
