From the saddle between Kastro and Hora, a surfaced road leads southwest to Episkopi. The remains here are believed to be those of a 3rd-century-AD Roman mausoleum that was transformed into a church in the 7th century and then became Moni Episkopis 10 centuries later. From here you can climb to a little church and ancient ruins perched on a precipice to the south, from where the views are spectacular.
