KK: /ˈprɒpɪˌleɪəm/
A structure that serves as an entrance or gateway to a temple or a group of buildings, often designed with architectural significance.
The ancient Greeks built a magnificent propylaeum to welcome visitors to their temple.
Propylaeum is derived from the Greek "pro-" (meaning before) and "pylai" (meaning gates). The term refers to a monumental gateway that serves as an entrance, typically to a temple or sacred area, thus indicating a structure that stands before the gates.
Think of 'before' ('pro-') and 'gates' ('pylai') to remember that a propylaeum is an entrance that stands before the gates.
