St Augustine Tower and Church complex ruins stand high up on the Monte Santo (Holy Hill) at Velha Goa (Old Goa). Built by the Augustinian friars who arrived in Goa in 1587, it was also the then site of the enormous church of Nossa Senhora da Graça (Our Lady of Grace). The Tower and the Church were built in 1602.

There is a rich history associated with this complex which is built in laterite stone. The picture is just of the ruins of the bell tower. The remains of its stone architecture is now a UNESCO Heritage site and is being preserved by The Archeological Society of India.

The St Augustine Tower site was also found to hold the precious remains of the Georgian Queen Ketevan. And, it is also the site of the Ketevan World Sacred Music festival held each year at the end of February.
