Initially a temporary royal residence, it was in the 10th century that Polonnaruwa was named the capital city of Sri Lanka. Anuradhapura was destroyed by King Chola Rajaraja I, and the dynasty chose Polonnaruwa as opposed to Anuradhapura as they were under the belief that it was easier to defend. To their dismay, however, King Vijayabahu I conquered Polonnaruwa in 1070, exiling the Cholas entirely. Afterwards, King Vijabahu adorned Polonnaruwa with several Buddhist monuments, which sit there, to this day, albeit in ruins. Polonnaruwa would continue to be the capital for three centuries, undergoing mass building projects under the king. King Parakramabahu undertook the building, constructing a multitude of parks, gardens, monuments and stunning palaces.
