Aathi Vinayagar temple is the only temple in the world where Vinayagar is seen with a human face. The rest of him will be with Elephant face. The temple is located at Poomthotam, about 4 hours drive south east of Thirchy towards Poompuhar. Vinayagar is seen with a human face, for he was such before he was slayed and his head replaced with a elephant head.
ps: I will try to Google search about this tonight. ;)
