Vandeur Mariman Thiakkulam is a beautiful square water reservoir spread over a vast area of about 16 acres, surrounding the Tibakulam temple in Madurai, which is one of the pilgrimage temples, where pilgrims come throughout the year to worship God Vigneshwara. The tank is the largest of its kind in Tamil Nadu, and has a distinctive design that includes staircases, statues and ornaments. Many religious celebrations are held here in this square, including the Flute Festival in February every year, which is a celebration of the birthday of King Thirumalai Nayak, the ruler of Madurai.
