ⓘ Giants Tank

Some historians have speculated that Giants Tank is the same as the Mahanama Matha Vapi tank built by King Dhatusena in the fifth century and restored by King Parakramabahu I in the twelfth century. On the other hand, Mudaliyar C. Rajanayagam in his book Ancient Jaffna suggests that the tank was probably constructed by the Nagas. Rajanayagam has suggested that the Megisba lake mentioned by Pliny in Description of Taprobane was in fact Giants Tank.

Attention was paid to the modernization of the tank during the Dutch Governor Willem Jacob van de Graafs administration in the eighteenth century, but nothing happened.
