Which term describes the construction on stage that suggests the time and place of the action?

The answer is "set/scenery".

Theatrical scenery is what is utilized as a setting for a dramatic creation. Landscape might be just about anything, from a solitary seat to an intricately re-made road, regardless of how vast or how little, whether the thing was uniquely crafted or is the certifiable thing, appropriated for theatrical use.
