[4] Archaeological and historical evidences suggest that Cholan, Kotte and Kandyan kings maintained strong relations with this temple in the past.

All Hindu temples in Tamil Speaking region are generally known as Thirukkovils adding the prefix 'Thiru' which means great or sacred.

The inhabitants of Eastern Sri Lanka praise that it is unusual to apply the sacred term "Thirukkovil" to not only a specific temple but to its whereabout too.

Kalinga King Bhuvaneka Gajabahu and his wife Cholan princess Thambathi Nallaal visited Batticaloa region during their way to Katirkamam.

Prasannajith, the kinglet of Batticaloa welcomed the royal couple and requested them to repair the chief temple of his country, Nagarmunai Subrahmanya Swami Kovil.

Thomas Christie, an Inspector of Hospitals of British Ceylon describes the antiquity of Sanctum, the sculptures and chariot belonged to Thirukkovil during his journey to Tangalle from Trincomalee in 1802.

Old Batticaloa District was divided into 8 "pattu"s (Administrative divisions) - Akkaraipattu, Karaivakupattu, Eruvilpattu, Manmunaippattu, Sammanthuraipattu, Porativupattu, Eravurpattu, Kiriwittipattu along with three other adjacent pattus - Koralaipattu, Panamaipattu and Nadukadupattu.

Necrolatry carried out in the shore of Thirukkovil sea on an Adi Amavasai is considered to give peace to the spirits of ancestors.

A Dutch merchant Johann Herman Von Bree states about the Annual Festival of Thirukkovil where the assembly of "Dessave" (Chieftain) and the thousand of people of Batticaloa happened in July month of 1603 CE.

The வண்ணக்கர் (Vaṇṇakkar, the Batticaloan equivalent post for head of trustee), belongs to Vellalar caste of Thambiluvil village played a main role in the administration while "வன்னியனார்" (Vaṉṉiyaṉār - former kinglet of Batticaloa region) of Karavakupattu, belongs to Paṇikkaṉā matriclan of Mukkuvar caste supervised the rituals and other main activities of temple.

Hence, Thirukkovil Temple could maintain its position as "Tecathuk Kovil" with the homage of the Tamil inhabitants of Southern Batticaloa - known as Ampara District today.

They still praise the guardian deity at Thirukkovil and celebrate his Mega fiesta "tīrttam" Festival annually with full of devotion and harmony.
