「斑馬知識+挑戰 」點解香港既海傍英文叫做 ”Praya” ?

Praya first appeared in Hong Kong around 1873.
Praya is a name to describe a walking path, especially near the seaside.
It was used during the colonial era. Many other colonies used this word.
It is a quite old term that people do not use them too often nowadays.

How's it different from "promenade"?
