What forge did Hephaestus make?

He was the god of forging and blacksmiths. His wife was Aphrodite (who didn't like him very much).

Hephaestus was the Greek god of fire, the forge, and blacksmiths. He was the patron of all craftsmen especially those that work with metals.

He was a hard-working, peace-loving god and was very fond of his mother. He was crippled and ugly as well.
