A kissing gate is a type of gate that allows people, but not livestock, to pass through. The normal construction is a half-round, rectangular, trapezoidal or V-shaped part-enclosure with the free end of a hinged gate trapped between its arms.
When the gate is touching an arm it must be pulled or pushed to pass through. The gate may need to be pushed to give access to the small enclosure, and when in the enclosure the person pulls the gate past the bulk of the enclosure to exit. Some examples have latches. Most are installed self-closing, to the side away from the pasture (livestock field), by hinge geometry, a spring or weight.
The name comes from the gate merely “kissing” (touching) the inside of the enclosure. It reliably forms a barrier rather than needing to be securely latched on each use. Examples, as with stiles, on footpaths published as accessible are those replaced, improved or supplemented by gates.
