Cos’è questo gigantesco edificio a Episkopi?

Hi, everyone!

I visited Kourion archeological site today and while admiring stunning views of the coast, I turned around and spotted this huge building with high columns and arches on the western part of the Episkopi village. I forgot to take a photo and later I wanted to find some info about it and I can’t find anything. I found it on Google Earth though, but that’s all.

It’s really interesting, since it really looks majestic in that small village. Can anyone tell anything about it? What is/was it used for?

Thank you in advance!
