The main objectives of the Society were set out as:
a) To preserve and study the antiquities of Tuam and the surrounding district.
b) To collect and preserve items of local and historical interest.
Under the direction of the Society, a survey of local antiquities was taken, a great many of which were found to be in a dilapidated condition, while the sites of others were virtually unknown.
As funds became available, the Society placed plaques, with informative inscriptions, at historic sites of importance.
