Arikamedu is an archaeological site of paramount importance in the history of Indo-Roman trade relations. Known as the port of "Podouke" in ancient Greco-Roman texts, this site was a major hub for bead-making and trading from the 2nd century BCE to the 8th century CE. The first mention of the site was in 1734 by a French consul, and formal excavations began in the 1940s, most notably by Sir Mortimer Wheeler. The excavations unearthed a treasure trove of Roman artifacts, including amphorae jars used for wine and olive oil, Arretine pottery, Roman lamps, and glassware. These findings provided concrete evidence of a thriving trade relationship between ancient Rome and the Tamil country. Today, what remains are mostly a few remnants of brick walls and a French Jesuit Mission House from the 18th century, but the historical significance of the site is immense. It's an open-air historical canvas, where the ruins and unearthed artifacts tell a story of a globalized world that existed millennia ago. The site is a testament to the fact that Ariyankuppam was not just a small fishing village but a bustling, cosmopolitan port that connected different parts of the ancient world.

The Church of Our Lady of Good Health, also known as Ariyankuppam Church, is a historical and revered Roman Catholic church. Its history dates back to 1690, making it one of the oldest churches in the Puducherry region. The church was originally built by the Armenians and later handed over to the Jesuits of the Carnatic Mission, who renamed it. The church is a popular pilgrimage site, drawing devotees from across the region who come to seek blessings and offer prayers to Mother Mary. The church's serene and peaceful atmosphere provides a perfect setting for quiet contemplation and spiritual reflection. The interior is decorated with beautiful rounded arches and wooden images of saints. The church is also known for its well-maintained premises and its role as a spiritual center for the local community. It is not just a place of worship but also a cultural landmark that reflects the town's French and Christian heritage. The church's simple yet majestic facade stands out amidst the bustling streets of Ariyankuppam, offering a sense of calm and tranquility to all who enter.
