he house stands opposite the West Gate of Government House, Mysore, and was the headquarters of the first Commissioners in Mysore, after the restoration of the Wadiyar dynasty. The rather utilitarian architecture seems to have been derived from that of the (East India) Company 'factories' or administrative buildings.

Immediately after the Fall of Seringapatam, Colonel Wellesley, was appointed Commandant at Seringapatam, where he occupied the Darya Daulat palace. He commissioned repairs to that building, and also to the Lal Bagh palace, but the latter fell into ruins after its British occupants left to take up residence at Mysore. Wellington Lodge was Arthur Wellesley's home from 1799-1801.

Wellesley's elder brother, Richard second Earl of Mornington, had been appointed Governor General of India in 1797 and arrived in April 1798. Arthur Wellesley had arrived in 1797, and succeeded in purchasing a number of military appointments to acquire the rank of Colonel. He commanded the 33rd Regiment at the age of 23. After the Fall of Seringapatam he was appointed to the Commission which his brother established, together with Lt. General Harris, Lt. Col. William Kirkpatrick and Lt. Col Barry Close, to determine the settlement of Mysore.

As a young Colonel in May 1799, Arthur Wellesley was not among the soldiers appointed for the final attack on Seringapatam. However, the experience gained on this campaign was seminal: Wellington in India had learned much from the sharp lessons of the final campaign against the Tiger of Mysore.
