This is a small church in Kastro, the most picturesque quarter of Chora (along with Little Venice). It is right next to the sea and the guide book said that the entrance doors of the Castle used to stand there, which is why the name of the church means "standing next to the doors". A beautiful church and impressively white. It is seen frequently in the postcards of Mykonos. I can't exactly describe you how to get there because the streets are too messing, you will just find it as you walk around.
