The Cankilian Thoppu is an archaeological protected monument in the Jaffna District and was listed as such by the Sri Lankan government in 2007.
The Cankilian Thoppu is located within the area known as the Pandiya Palace, which supports the connection with the Tamil kings and their kingdom.
[3] The Cankilian Thoppu arch was reconstructed in 2023 as a part of a larger, ongoing effort to restore Tamil heritage sites, including the Jaffna Palace ruins.
The wall and pathway to the Cankilian Thoppu were reconstructed as well to increase public access to the site.
The reconstruction project was also sponsored by Jaffna Heritage Center, an organization based in Northern Sri Lanka.
