For over 200 hundred years, Mystras was a thriving kingdom until the fall of the Byzantine Empire. Today on the steep hillside is a collection of ruined churches, some are in better shape than others. Some even retained their beautiful frescoes. This is an UNESCO world heritage site. I was here 10 years ago and it has always been my intention to return. The best time to visit is early to late Spring when the whole place is filled with wildflowers. This is one of the best places in the world to see wildflowers.
