Gallery

In broad terms, in North American usage the word gallery alone often implies a private gallery, while a public gallery is more likely to be described as an art museum. In British and Commonwealth usage, the word gallery alone implies a public gallery, while a private or ... commercial gallery will be distinguished using those terms, and the word museum alone is generally understood to refer to institutions holding collections of historic, archaeological or scientific artefacts, rather than of fine art. — en.wikipedia.org
