Pulithevan Palace
Pulithevar is regarded as the first South Indian ruler, who sowed the seeds of his gallant resistance to expel the foreigners from the soil. The vivacity of his character gave him an ascendancy over the western palayakkars, while his determined resistance to the Nawab's over lordship made him a potential enemy of the Wallajahs. In order to honour his services to the nation, Tamil nadu Government has erected a memorial for him in Nelkattumsevval or Avudaiyapuram in Sankarankoil taluk where there is a remnant of his palace.
