Thiruvalla copper plates

Thiruvalla copper plates, also known as the Huzur Treasury Plates, are a collection of medieval temple committee resolutions found at the Sreevallabha Temple in Thiruvalla, Kerala, India.^[1] The collection of plates, engraved in Vattezhuthu with some Grantha characters, can be dated to 10th and 11th centuries AD.^[1]

The collection consist of forty three plates with writing on both sides, but more than half a dozen plates are missing.^[1] The contents of the copper plates belong to different periods. The plates were collected, rearranged and edited at a late date. The plates are considered as a treasure trove of information about medieval temple rituals, deities, festivals, castes, professions, personal names, plot names, and prices.^[1]

The plates were first published in Travancore Archaeological Series by T. A. Gopinatha Rao, under the title "The Huzur Treasury Plates".^[1] They were originally kept in the Sreevallabha Temple, Thiruvalla (now with Archeological Department of Kerala).^[1]
