The king initially divided the city into four districts or suburbs, each marked with its own alms-giving house for the clergy, containing "vessels of bronze, cushions and pillows, mats, carpets and bedsteads". He ordered the construction of hospitals, which he visited on several occasions. He also expanded Polonnaruwa's defensive walls, constructing an elaborate three-walled complex featuring turrets for archers and fourteen gates. None of which has survived till modern times. Beyond the city precinct it is believed he constructed or renovated three smaller townships, in addition to Parakramapura - Rajavesi Bhujanga, Raja Kulantaka (Sinhapura), and Vijitapura. Extensive gardens were also laid down around Polonnaruwa, featuring ponds and bathing-pools, one of which, the Twin Pools, survives till this date. One such garden, the 'Island Garden', extended into the middle of Thupa Vewa ('Vewa' meaning 'tank' or 'reservoir' in Sinhala) on a promontory.
