A smithy is the place where blacksmiths do their work, heating and shaping metal, especially to make tools. You can also call the blacksmith a smithy.
Smithy is an old-fashioned word for an old-fashioned profession. A smithy's job involves heating metal and hammering it into the shape of things like axe heads or horseshoes. The workplace itself is less likely to be called a smithy these days and is more commonly referred to as a forge. Smithy and smith can both be traced back to a Proto-Indo-European root word that means "to cut."
