The grateful public of Ceylon erected a statue in memory of Sir Charles Henry de Soysa of Moratuwa, opposite Victoria Memorial Eye Hospital, Colombo. This statue shows Sir Charles holding a key in his hand to signify that he was ever ready to open his vault and give to the deserving of all faiths.
His munificence knew no bounds. He donated the Victoria Memorial Eye Hospital, the Lunawa Hospital, the Bacteriological Institute, the Holy Emmanuel Church, Moratuwa, two large schools, Prince and Princess of Wales Colleges, the Soysa-ramaya Buddhist Temple, several "ambalamas" on the road to Kandy and Marawila where his plantation interests were, and the De Soysa Maternity Home. Sir Charles entertained Royalty at "Alfred House" Kollupitiya. He died on September 29, 1890.
