Markooh Castle in the heights of the Alborz Mountains near the city of Ramsar is an old military fortress that dates back more than eight centuries.
To get inside the castle one needs to climb some 300 stairs. Unfortunately, this historical site has not been thoroughly studied by archeologists.
Markooh Castle is visited by many tourists each year and is one of the most beautiful tourist attractions of the Caspian province of Mazandaran.
