A storehouse of valuables is often referred to as a 'TROVE'. A TROVE is a collection of valuable items, such as money, jewelry, or other precious objects. It can also refer to a large collection of documents, books, or other items of historical or cultural significance. The term is derived from the Old French word 'trouver', which means 'to find'. A TROVE is typically hidden away and kept safe, making it a valuable asset for those who possess it.
