The Gal Pota (Stone Book) is a colossal stone representation of an ola book. It is nearly 9m long by 1.5m wide, and 40cm to 66cm thick. The inscription on it – the longest such stone inscription in Sri Lanka – indicates that it was a Nissanka Malla publication. Much of it extols his virtues as a king, but it also includes the footnote that the slab, weighing 25 tonnes, was dragged from Mihintale, an astonishing 100km away.
