The farmhouse, from the family album
Next door to history: Marconi, May 1897
In May 1897 Guglielmo Marconi and William Preece, engineer-in-chief of the Post Office, tested wireless telegraphy across the Bristol Channel at Lavernock Point, about 5 km south of Llandough.
Signals crossed open sea from Flat Holm island to Lavernock, and on 18 May from Lavernock to Brean Down in Somerset. A plaque at St Lawrence’s church, Lavernock, marks the trials.
The tour will tell this story beside the farm’s own.
