A boundary without the visible fenceSourced
The ha-ha keeps animals out while preserving the view
A ha-ha uses a sunken ditch and steep wall to restrict access, such as keeping grazing livestock out of a garden. It avoids obstructing the view, making garden and landscape appear continuous. An unobvious boundary is still a boundary.
The uninterrupted vista can contain a hidden barrier.
