Eu Tong Sen was a well-known tycoon in the late 19th and early 20th centuries with business interests across Southeast Asia. He was also vice-president of the Anti-Opium Society and a somewhat eccentric property owner. Heir to his family’s retail and mining businesses, he took control of his father’s estate in 1898. Over the decades that followed, he multiplied his fortune several times over. By age 30, he was one of the region’s richest men, specialising in the tin mining and rubber industries.
Eu built three castles in Hong Kong – Eucliffe was the most well-known. It was famous for being a social hot spot in the 1930s and was located next door to the Kadoorie’s Repulse Bay Hotel. The folly featured a large collection of ancient western armour as well as stained glass windows.
