what beautiful place in bangkok that sounds like iyota?

ruby, my college classmate, who worked in bangkok was selling bangkok to us.
she was enumerating some of the places she’ll tour us in case we’ll go there.
and, she mentions ayutthaya to us.
of course, the virginal crowd, was only able to process the word as ‘iyota.’

when i see this post, nalingaw ko.
so this is what’s the place about.
it’s about ancient ruins, and nothing about ‘red light district’ in thailand.
