KK: /ˈʃoʊˌpleɪs/
A place, such as a building or estate, that is admired for its beauty or significance and is often shown to visitors.
The historic mansion is a popular showplace that attracts many tourists each year.
Showplace is formed from "show" (from Old English "sceawian", meaning to look at or to see) and "place" (from Old French "place", meaning a space or area). The word "showplace" refers to a place that is intended to be shown or displayed, often for its beauty or significance.
Think of a place that is meant to be 'looked at' ('show') and is a specific 'area' ('place') — that's why a showplace is a place meant for display.
