Thian Hock Keng is one of the oldest and most important Hokkien temple in Singapore. It was visited by Chinese immigrants giving thanks to Ma Zu (Goddess of the Sea) for their safe voyage.

In 1839, under the leadership of Mr Tan Tock Seng and Mr Si Hoo Keh, the Hokkien clan built the temple in Telok Ayer Street. It also housed the clan's office and served as a meeting venue. The construction of Thian Hock Keng was completed in 1842.

Thian Hock Keng which is managed by Singapore Hokkien Huay Kuan was gazetted as a national monument in 1973. Over the years, Thian Hock Keng has been restored several times. The most comprehensive one commenced in 1998 and was completed in December 2000. This restoration project won 4 architectural awards, including the most prestigious award from UNESCO Asia-Pacific Heritage 2001 Awards for Culture Heritage Conservation Building.
