It was originally a Jain temple which was later used as residence by the Irish mercenary adventurer George Thomas (c. 1756 – 22 August 1802).

Originally press-ganged at Youghal, where he worked as a labourer on the docks, Thomas deserted from the British Navy in Madras in 1781.

Still illiterate, he led a group of Pindaris north to Delhi by 1787, where he took service under Begum Samru of Sardhana.
