Tissamaharama stupa had developed a series of vertical cracks right round the dome of the stupa and in some other parts around in 1990. The department of Archeology of Sri Lanka and State Engineering Co-operation intervened on the request of chief incumbent of the temple and prevented further cracking of the stupa by using galvanized steel cables tied around the circumference of the dome in the mid section. This final repair works were completed in February 1998 at a total cost of 6 million Sri Lankan rupees.
