On the northern edge of the Lahugala National Park are the ruins of a substantial ancient temple now called Magul Maha Vihara. This temple is worth a visit not only because of its particularly attractive forest setting but also because the image shrine, the Bodhi Tree and the stupa are all in a good state of preservation.
Ven. Hulanduwe Ratanasara Thera the 5th generation descendent of the Uva-Wellassa lineage which administered the Magul Maha Vihare is the present Chief Priest. Lahugala belonged to the Ruhunu Kingdom of ancient Lanka. The entire Vihara complex had covered an extent of around 10,000 acres where ruins of a palace, moonstone, monastery, bo-maluwa, stupas, ponds etc. were found scattered all over. A headless white marble Buddha statue was seen lying horizontally in one part of the ruins.
