The Gazebo now stands at the side of a residential street, but originally it was part of larger gardens.
Thanks to Neil for the following info :-
The house dates from the late 1700’s and so does the gazebo. Until the early 1960s the house was owned by a doctor who held his surgeries there. The main house was split into two in the mid 1960s and my Aunt and Uncle have lived there since then. The cottage at the end may be older and may have been two residences since it had two staircases one of which has been removed. The gazebo would have provided a view of the sea beyond the garden wall.
