means A building or institution where objects of artistic, historical, scientific, or cultural value are collected, preserved, and put on display for the public.

from From Latin museum, itself borrowed from Greek mouseion, meaning a 'seat or shrine of the Muses' — the nine goddesses who presided over the arts and sciences. The most famous early mouseion was at Alexandria: not a gallery of relics but a research institution and library where scholars gathered under the Muses' patronage. The word kept that scholarly flavor for centuries before settling, by the 17th century in English, into its modern sense of a place where collections are kept and shown.
