Both pillars of this aḷavukkalA sort of gate, which is used for measuring the height of the water in tanks. bear fragments of ancient inscriptions. That on the right pillar belongs to the time of some Ko-Parakesarivarman. It deserves to be noted that, in line 3, the syllable ṟā is written ṟā [[றா]], and not ṟā [[prereform ṟā as a single glyph]] as in modern Tamil.
