Completed in 1930, Tintagel was intended as a residence for Dr. Lucian de Zilwa. In the mid 1940s de Zilwa was given a week to vacate the property by the British military to house one hundred soldiers. The military occupation saw the house wrecked and de Zilwa sold Tintagel to sir Solomon Dias Bandaranaike for his son, Solomon West Ridgeway (S.W.R.D.). It is from this point in time that the house gained recognition as a structure of national importance.
It was here that Ceylon’s political history was decided. S.W.R.D. Bandaranaike became prime minister in 1956 and he was shot on the verandah of Tintagel in 1959 and subsequently died in hospital.
