The next three centuries starting from 1215 were marked by kaleidoscopically shifting collections of capitals in south and central Sri Lanka, including Dambadeniya, Yapahuwa, Gampola, Raigama, Kotte, Sitawaka, and finally, Kandy. Chinese admiral Zheng He and his naval expeditionary force landed at Galle, Sri Lanka in 1409 and got into battle with the local king Vira Alakesvara of Gampola. Zheng He captured King Vira Alakesvara and later released him. Zheng He erected the Galle Trilingual Inscription, a stone tablet at Galle written in three languages (Chinese, Tamil, and Persian), to commemorate his visit. The stele was discovered by S. H. Thomlin at Galle in 1911 and is now preserved in the Colombo National Museum.
