Which Hindu deity is the divine architect?

Vishwakarma is the divine architect of the gods, or devas, in Hindu tradition.

He is portrayed as a master craftsman, builder, engineer, and designer of celestial structures. Hindu texts credit him with creating divine weapons and chariots, including Indra’s thunderbolt, the vajra. He is also associated with the construction of legendary cities such as Lanka, Dvaraka, and Indraprastha.

The figure has a long textual history. In early Vedic literature, Vishvakarman was an epithet meaning “all-maker” or “creator of everything,” rather than always being a separate personal deity. The older craftsman deity Tvastr performed a similar role, and later traditions sometimes identify or merge the two figures.

Vishwakarma is especially important to artisans, engineers, architects, craftspeople, and factory workers. Vishwakarma Puja is observed in many parts of India, commonly around September 17 or 18. Brahma is chiefly the creator, while Indra is the ruler of the Devas, so neither is the canonical answer to this question.
