The Thousand Lights Mosque at the junction of Anna Salai and Peters Road in Royapettah is the main centre of Shia Muslims in Tamil Nadu, and it gave its name to the whole neighbourhood and to a metro station. Tamil Nadu Tourism explains the name with a legend that a thousand lamps were needed to light the prayer hall. Its cream-coloured domes and minarets are among the most recognisable sights on Mount Road.
The present building is newer than many people assume. The site’s religious use dates from 1810, the mosque from about 1820, and the structure you see from the road from a rebuilding around 1900. Here is how it grew, what it is used for, and how to visit respectfully.
From a garden house to an Ashurkhana
In the late eighteenth century the land was part of a garden estate on the Great Choultry Plain, the open country south-west of the old city. The Quint traces it to a garden house built by a Madras mayor, George MacKay, later bought by the Nawab of the Carnatic’s family.
In 1810 the Nawab’s son, Umdat-ul-Umara, built an assembly hall here for Shia mourning ceremonies, an Ashurkhana. A writer quoted by historian Andrew Whitehead says it was a relative of the Nawab who lit the assembly ground with a thousand oil lamps during Muharram, which is where the name comes from. About ten years later a mosque was built in front of the Ashurkhana.
Rebuilding and the building today
The mosque was rebuilt around 1900 and has been modernised at least twice since, according to Whitehead’s account of a 2018 visit. Its caretaker told him there was a Malaysian connection to the building or its refurbishment.
Tamil Nadu Tourism describes the complex as follows:
- Several domes and tall minarets in a medieval Islamic style, with verses from the Quran on the walls.
- A main prayer hall for men on the ground floor and a separate room for women’s prayers.
- A dargah, the most sacred part, on the second floor.
- A library and a guest house within the complex.
Whitehead also describes a large, well-kept graveyard on the grounds. The chief Shia religious office in the city has long functioned from here, which is why the mosque acts as something like the community’s headquarters in the state.
Muharram and Ramzan
The mosque is dedicated to the memory of Imam Hussain, the Prophet’s grandson, whose death at Karbala Shia Muslims mourn during Muharram. During those days devotees gather for the matam, the ritual of mourning, and the mosque is decorated with lights, Tamil Nadu Tourism notes. Processions and gatherings on Ashura can slow traffic on Anna Salai and Peters Road, and police usually announce diversions.
In Ramzan the mosque serves nombu kanji, the rice gruel cooked in large vessels for breaking the fast. The Quint described a quiet iftar in 2017 where families broke their fast together inside the complex.
How to visit
The mosque is an active place of worship first and a sight second. These points help:
- Time it right. Avoid the five daily prayer times and Friday midday prayers if you want to look around. Early afternoon on a weekday is usually quietest.
- Dress modestly. Cover arms and legs. Women should carry a scarf for their heads.
- Ask at the entrance. Non-Muslim visitors are often allowed into the courtyard, but access to prayer halls is at the discretion of the caretakers.
- Remove footwear where indicated and keep your voice low.
- Ask before photographing people or the interior.
Getting there: Thousand Lights station on the Chennai Metro’s Blue Line, listed on the CMRL website, is a short walk away along Anna Salai. Many MTC buses run along Anna Salai, and autos can drop you at the Peters Road corner.
Around the mosque
Thousand Lights was once a district of large mansions belonging to the Nawab’s relatives and wealthy families, and pockets of that past survive in the lanes off Peters Road and Royapettah High Road. The Wallajah Big Mosque in Triplicane, built by the Sunni Nawabs, is a short drive east and makes a good pairing for anyone interested in the Arcot Nawabs’ legacy in Madras.
