The temple is unique in its architecture as it blends the style of the French with the traditional Deccan architecture of India.
The temple of Kanniga Parameswari is dedicated to the Goddess Shakti who is the representative deity of power in Hindu mythology. Shakti is another form of the powerful Goddess Kali who is one of the popular deities worshiped in Pondicherry and also in the whole country. The monumental structure of the temple is a blend of French and Tamil architectural styles.
The interior ceiling of the sanctum is designed in the traditional style of the Tamil architecture and contains motifs on the granite pillars. The construction stands on monolithic pillars that represent the architecture of Europe. The walls of the temple are arched and are ornamented and beautified with angels and heavenly creatures designed on them. These along with the stained glass panes are archetypes of French places of worship. Other than the main sanctum sanctorum, most of the temple structure is designed in French architectural style.
Devotees and pilgrims from all over the country gather to offer their prayers and seek the blessings of the presiding deity of the temple. Hindu marriages are also conducted in the temple premises. The Kanniga Parameswari Temple still retains the magnificence and uniqueness that was present when the temple was initially constructed ages ago.
