The huge Kalutara Temple marks the entrance to the town; located across the Kalutara Bridge the shrine occupies both sides of the main road. Home to the world's largest hollow stupa, this temple is a huge pilgrimage site more so, for the Bo Tree growing along the banks of the river. The tree is believed to be one of the saplings brought down from India, originating from the very tree the Buddha attained Nirvana under. You will discover a fine collection of vintage art displayed within the stupa, while roadside tills are filled up by passing travellers, who pray for blessings and a safe journey. Located just 4kms from Mermaid Hotel & Club, the temple is a charming place to visit at night, especially on a full moon poya day.
