The Wijaya Kumarathunga Memorial Hospital was established by an Act of Parliament referred to as “ The Wijaya Kumarathunga Memorial Foundation Act No. 31 of 1998” and published in the Gazette of the Democratic Socialist Republic of Sri Lanka on 12th November 1999.
The Wijaya Kumarathunga Memorial Hospital was established in memory of late Mr. Wijaya Kumarathunga who was assassinated on 16 February 1988. Reverend Fr. Sunanda Wanasinghe, Parish Priest of Seeduwa, suggested to the then President of Sri Lanka Her Excellency Chandrika Bandaranaike Kumarathunga that the best way to perpetuate the memory of the humanist Wijaya Kumarathunga would be to build a hospital to serve the people of the area where Wijaya Kumarathunga was born, bred and lived. The suggestion was accepted.
A hospital consisting of two wards (60 beds) and an OPD was constructed by the Wijaya Kumarathunga Memorial Foundation on a three acre block of land at Seeduwa along the Colombo Negombo Highway within the limits of Katunayake/Seeduwa Urban Council. The hospital was officially opened to the public by Her Excellency then President Chandrika Bandaranaike Kumarathunga, on the 09th of October 1999, the birthday of Mr. WijayaKumarathunga.
While the Board of Directors take the policy decisions, the operational and administration of day-to-day management of Wijaya Kumarathunga Memorial Hospital has been vested in the Wijaya Kumarathunga Hospital Board by “Wijaya Kumarathunga Hospital Board Act No. 38 of 1999” and published by a Government Gazette of Democratic Socialist Republic of Sri Lanka.
As part of development, a separate building was constructed consisting of an Eye Ward with 88 beds in the year 2004 bringing the total number of beds to 148. With a view to providing a high quality service to the public, the existing standards were enhanced and a full fledged eye ward was opened during the year 2007.
At present the bed strength has been increased up to 156 by converting all the unoccupied idle space for the use of patients.
During 2011 a separate two storey building was constructed for the purpose of General stores, Medical record room, Duty rooms and a lecture hall, etc.
