The stream known as Peraru (Per Aru) originates in the eastern part of Vavuniya District and joins the sea at Nandikadal Lagoon in Mullativu. A remains of an ancient Amuna (anicut) can be seen across Peraru Oya in Grama Niladhari domain of Muthyankattuwa (Muthian Katti Kulam) in Oddusudan area.

In ancient times, low embankments built across rivers and other streams were called an “Amuna”. These embankments diverted the water of the river to other canals and were used to fill fields or other tanks.

From the shape of the pin holes made in the stone slabs used to make this Amuna, it is clear that this was built during the Anuradhapura era. One river bank of two of the embankments has been systematically prepared using gravel and stone blocks, and the second bank has been prepared using natural rock and embankments have been placed only in the necessary places.

The stones of the embankment across this stream have recently crumbled. It is very clear that the ancients have chosen the most suitable place for the creation of the embankment as this is the place where the Peraru Oya narrows due to the natural rocks in its path.

reachable From Oddusudan, you can go towards the Muthyankattukulam reservoir and walk along the southern canal for about three and a half kilometres to reach this embankment. A yellow archaeological board has been installed showing the final footpath towards Peraru Oya. Its direction is indicated and it is mentioned as an archaeological site. But as of today, I don’t know if this board is still available.
