Sri Mariamman Temple, Singapore in the context of "Sacred architecture"

Sacral architecture (also known as sacred architecture or religious architecture) is a religious architectural practice concerned with the design and construction of places of worship or sacred or intentional space, such as churches, mosques, stupas, synagogues, and temples. Many cultures devoted considerable resources to their sacred architecture and places of worship. Religious and sacred spaces are amongst the most impressive and permanent monolithic buildings created by humanity. Conversely, sacred architecture as a locale for meta-intimacy may also be non-monolithic, ephemeral and intensely private, personal and non-public.

Sacred, religious and holy structures often evolved over centuries and were the largest buildings in the world, prior to the modern skyscraper. While the various styles employed in sacred architecture sometimes reflected trends in other structures, these styles also remained unique from the contemporary architecture used in other structures. With the rise of Christianity and Islam, religious buildings increasingly became centres of worship, prayer and meditation.

Hindu religion and culture in Singapore can be traced to the 7th century AD, when Temasek was a trading post of Hindu-Buddhist Srivijaya empire. A millennium later, a wave of immigrants from southern India were brought to Singapore, mostly as coolies and indentured labourers by the British East India Company and colonial British Empire. As with Malay peninsula, the British administration sought to stabilise a reliable labour force in its regional plantation and trading activities; it encouraged Hindus to bring family through the kangani system of migration, settle, build temples and segregated it into a community that later became Little India.

There are currently about thirty main Hindu temples in Singapore. There were an estimated 172,963 Hindus in Singapore according to the 2020 Census constituting 5.0% of the Singapore's resident population. Almost all Hindus in Singapore are ethnic Indians (99%), with some who have married into Hindu families. Hinduism peaked at 5.5% of the total population in 1931.
