King Pandukabhaya (437 BC – 367 BC)

Son of Unmadha Chitra (Queen – Suwannapali) – Capital changed to Anuradhapura

King deepened a pond in Anuradhagama, filled it with water, and took water from this pond for his consecration festival. Hence this deepened pond was called Jayavapi.

(Author’s Note: Mahavamsa states that a pond was deepened and filled with water. How it was done is not stated. It can be deduced that the pond was filled with water using a canal. Jayavapi is suspected to be Bulan Kulam in Anuradhapura).

King Pandukabhaya built a great city where Anuradha Gama was located, named it “Anuradhapura”, and made it the capital city of Lanka. He built many villages, castles, sewer systems, hospitals and cemeteries.
King Pandukabhaya built Abhaya Vapi (today known as Abhaya Wewa in Anuradhapura), a common cemetery, a place for executions, a place of worship and a house for sacrifice. King built a hermitage for Nigantha ascetics near Gaminivapi. (Here Mahavamsa accidentally mentions another reservoir – Gaminivapi, identified as Karambewa reservoir in Anuradhapura. Did Deega Gamini build Gaminivapi?)

Abhaya Wewa: Basawakkulama (400 BC) – (Author’s Note)

Only Panda Wewa is older than King Pandukabhaya’s Abhaya Wewa. Pandukabhaya was the grand son of King Panduvasdev.
Abhaya Wewa was much smaller than Panda Wewa. (Abhaya Wewa is only 330 acres compared to Panda Wewa, which is 1,360 acres). The reason for the smaller size of the reservoir could be attributed to the fact that Abhaya Wewa was built inside the capital city of Anuradhapura.

Main purpose of Abhayawewa was to provide water for the city population for drinking and bathing. The embankment of Abhaya Wewa is 5,910 feet long and 22 feet high. The slope of the embankment was found to be three horizontals to one vertical. Top of the embankment has a width of six to eight feet. Slope of Abhaya Wewa was flatter than that of Panda Wewa. It could be due to the fact that later designers decided to build the embankment stronger. Reservoirs, which were built after Abhaya Wewa, had much flatter embankments, and in some cases exceeded four horizontals to one vertical.

Author’s Note: Abhaya Reservoir (Ref: Seeing Ceylon, R.L Brohier)

“Basawakkulam (Abhaya reservoir) lying in a shallow valley with its waters held up by an earth bund whose concave side faces up-stream claims pride of place as the oldest of the three Anuradhapura city reservoirs. (Nuwara Wewa, Tissa Wewa and Abhaya Wewa). Abhaya reservoir was built after Pandukabhaya, an intelligent young King assumed rule over the kingdom. There is nothing in the structure to indicate its antiquity, but if evidence be needed of the remarkable achievement of that early unnamed hydraulic engineer who designed it, there is proof that this structure remains unbreached even after the thrilling history of Anuradhapura, with its unique records of conquests, dynastic ambitions, regal triumphs and tragedies, had ended on the crest of a mighty wave of invasion 1200 years after the city was founded”.

Author’s Note: (Components of a Reservoir):

Ancient reservoirs in Sri Lanka (Wewa) have following major components.
1. Bund or embankment to hold water. (Bund is known as “Waw Kandiya” in Sinhalese).
2. Sluice to obtain water from the reservoir. (Sluice is known as “Sorowwa” in Sinhalese).
3. Spill to remove water during major flood events. (Spill is known as “Pitawana” in

Bund: (Built using soil)

Ancient reservoirs bund

Ancient reservoir bunds were built with soil. If water flows over the bund, that bund would fail. Water should never be allowed to flow over the bund.

Spill (Pitawana): (built using rock) During flood events, water is allowed to go over the spill. Spill is built using rock. Spill will not fail when water goes over it. On the other hand as mentioned earlier, bund would fail if water goes over it, since the bund is built using soil.

ancient reservoirs spill

Ancient Engineers had to decide whether the length of the spill is enough to remove all the water during a major flood. If the length of the spill is not enough, water would rise and go over the bund. Then the reservoir bund would fail. As mentioned earlier, water should never be allowed to go over the bund.
In the case of Kalawewa, spill was 170 feet long and 216 feet wide!. (Compare this to a length of a soccer field of 300 ft). Early British investigators believed that the spill of Kalawewa was over designed. Later studies proved that the ancient Engineer was right since flood water could accumulate very fast during major flood events and longer and stronger spill is required to remove the water quickly to save the reservoir bund.

Canals (Ela):
A large canal would carry water coming out of the sluice. This large canal would feed smaller canals.
These smaller canals would feed much smaller canals. Finally, water would end up in paddy fields.

“It was this invention alone which permitted the Sinhalese to proceed boldly with the construction of reservoirs that still rank among the finest and greatest works of the kind in the world. Without some efficient means of regulating the discharge of the water through the sluices, the provision of reservoirs for storing water could never have extended beyond
the minor tanks”.
(Ref: H. Parker, Ancient Ceylon)


Biskotuwa is a device used by ancient engineers to control the outflow of water from wewa with considerable heights (10-15m). As shown in figure 7, the Bisokotuwa consists of a rectangular tank connected to the sluice; in almost all the cases the longer side of the rectangle is kept parallel to the bund. Water comes from one side and leaves from the other side. Wooden sheets were placed inside to regulate the flow.

After the death of King Pandukabhaya, his son Mutaseewa was consecrated as King of Lanka.

King Mutaseeva (367 BC – 307 BC)

(Fifth King of Lanka) – Son of King Pandukabhaya
King Mutaseeva’s main work included the construction of the Mahamevna Uyana, (Mahamevna Garden in Anuradhapura). It was created with many fruit trees and flowering trees. King Mutaseewa had ten sons and two daughters. After the death of King Mutaseeva, his second son “Devanampiya Tissa” became the King of Lanka.

    What’s the meaning of ‘Unmaada Chithra’? Mad Chithra. If somebody getting mad about her she must be call ‘Unmaadani’. Not ‘Unmaada’. She was mad because she had been prisoned for a long time. Not Sakkya clan Deegagamini but Yakka Pandula came and raped her and gone. Later he taught Abhaya all the things and gave money and soldiers to him. Abhaya was called after him. ‘Pandu-ka-Abhaya’.(Panduge Abhaya)
    According to archaeologists this Pandvas Nuwara was not built by King Panduvasa. It was built by King Parakramabahu Do you know he was the grandson of South Indian Pandya king? Panda was that panda.
    King Pandukabhya was a international trader. He built a centre at the western side of the city for ‘Yavana’ merchants. Geiger thinks these Yavana must be either Greek or Muslims.
    The great king introduced ‘Gam Sabha” to the country.

    @Thilaka Randeni it was Chittaraja who made Chittra pregnant. Pandula was the one who trained Pandukabhya. That is the reason why the the local natives accepted him because he was of Yakka bloodline and he’s from the house of Vijaya through his Aryan mother. Thus being the first native king with an Aryan mother

    For those who think that we Sinhalese are descendants of Vijaya, this is just to let you know that the children that he got from Kuweni were Jeewahatha and Disala are the ancestor of the Veddas.

    The actual Sinhalese History is more than 33000 years old but didn’t exist as Sinhala but Siwhela which were the yakka, naga, deva and Raksha. Later King Pandukabhya united these tribes to form the Sinhala race and that’s why the Sinhala (siw -hela) race is 2400 years. But everyone please note that the actual history is more than 33000 years old.

    Be proud Sinhalese people, we are native to our motherland Sri Lanka

    @Kevin Actually Chithraraja was not Pandukabhaya’s father. The king was named after his father Pandula. All of them belong to Yakka nation. In east province of Lanka there was a great agreement in Panduvasa time. According to that Chithraraja, Kaladeva came to Upathissagama and joined state service. After that Valavamukhi who was pregnant by Pandula Bamuna, came and settled in the palace with the recommendation of Chithraraja. Then at auspicious time Pandula came to the palace and by the Karakataka machine climbed in to the tower and raped Unmada-Chithra and gone away. After that you know what happend

    If you are interest in history go to the Youtube and search for hela abimanee. At the moment they have upload only 8 programs. In my ??????? ??????? you can read more.
