Vishvakarma or Vishvakarman is a craftsman deity and the divine architect of the devas in contemporary Hinduism. In the early texts, the craftsman deity was known as Tvastar and the word "Vishvakarma" was originally used as an epithet for any powerful deity. However, in many later traditions, Vishvakarma became the name of the craftsman god.

In the Hindu epic Ramayana, Nala, is the vanara (monkey), who is credited as the engineer of the Rama Setu, a bridge across the ocean between Rameswaram and Lanka, identified with modern-day Sri Lanka, so forces of the god Rama can pass over to Lanka. The bridge is also known as Nala Setu, the bridge of Nala. Along with Nala, another vanara who is his twin brother called Nila is also credited as the builder of the bridge. Nala is described as the architect of the vanaras. He is described as the son of the architect-god Vishwakarma. Nala is also described to have fought in the battle between Rama and Ravana, the king of Lanka.
