Thousand Lights is a multi-domed mosque in Anna Salai in Chennai, Tamil Nadu, India, is one of the largest mosques in the country and is a revered place of worship and azadari for Shia Muslims in the city.
The mosque was built in 1810 by Arcot Nawab Umdat ul-Umara.[1] It was constructed in medieval architecture.[2] The site of the mosque was previously occupied by an assembly hall. There was a tradition of lighting thousand oil lamps to illuminate the assembly hall. The mosque thus gets its name from this tradition.[3]
The chief Shia Qazi of Chennai functions from the mosque, and the post has been continuously held by the same family.[1]
