There were many Hindu temples within the Kingdom. Some were of great historic importance, such as the Koneswaram temple in Trincomalee, Ketheeswaram temple in Mannar, Naguleswaram temple in Keerimalai along with hundreds of other temples that were scattered over the region. The ceremonies and festivals were similar to those in modern South India, with some slight changes in emphasis. The Tamil devotional literature of Saiva saints was used in worship. The Hindu New Year falling on the middle of April was more elaborately celebrated and festivals, such as "Navarattiri", "Deepavali", "Sivarattiri", and "Thaiponkal", along with marriages, deaths and coming of age ceremonies were part of the daily life.
