In one of my trips I saw a plate which indicates to Soimos fortress but I didn’t had enough time to visit it so I came back after some days.
We were surprised about the way you need to get up there (no path just a grass road like that) and the weather was so hot I was just exhausted.
But it was worth it because the view from there was amazing.You can see the city and the river that cross it.Unfortunately I don’t have in my phone that picture,but you should go and watch that in real life.
