Parākramabāhu's objective for Dakkhinadesa was to expand it so that it would surpass the greatness of other kingdoms, in a short period of time. He started a huge program of construction and renovation, the remnants of which can still be seen in North Central Province, Sri Lanka, today. It is mentioned of him as having restored an ancient causeway called the Kotabaddha, over the Deduru Oya (Deduru Lake) near modern Kurunegala. The new king's personality was illustrated when the architects commissioned to the project informed him that it was well-nigh impossible to carry out, to which Parākramabāhu replied that "What is there in the world that cannot be carried out by people of energy?". He ordered the construction of canals and dams, and cleared a large area of forest around them for new fields. Most notably, he constructed the Parakrama Samudra, a giant reservoir from which a large swathe of territory derived its water supply. On islands in the middle of the reservoir he constructed a palace and a stupa.
