What is it? It is the first circular underground reservoir and one of the oldest to exist in Hong Kong. After this historic structure was discovered in 2020, it was rated as a Grade I historical monument by the Antiquities Advisory Board.
Why go? Its architecture and structural design is truly impressive. Modelled after ancient Roman engineering, it features striking granite columns, red brick arches, and semicircular channels that offers a glimpse of Hong Kong's past. Wander the grounds and you'll be transported back in time, with the afternoon sun filtering through to cast a mesmerising, almost mystical glow. The best part is, it's open to the public for free with no pre-registration required.
