Nallur Kandaswamy Temple Annual Festival in Jaffna/Nallur
A twenty-five-day Hindu festival at Jaffna's Nallur Kandaswamy Temple honoring Lord Murugan, timed to the Tamil lunar calendar in August or September, featuring elaborate vahana processions with statues carried on peacock, cobra, and swan-shaped vehicles and culminating in a massive chariot procession on the festival's 24th day.
The Nallur Kandaswamy Temple's annual festival is widely described as Sri Lanka's longest single religious observance, stretching across twenty-five consecutive days each year in Jaffna in honor of Lord Murugan, the deity to whom the temple is dedicated.
