The ancient and vicissitudinous Lin Castle.

The mud buildings of the Nalin Castle have collapsed in many places, and some protective measures have been taken with scaffolding. The adobe building complex can be traced back to the Sassanid period. The castle is an important defensive fortification in ancient Persia and is also the oldest surviving adobe building in Iran. The erosion of time has caused serious weathering. Climbing up the castle, touching the ancient walls, you can clearly see that the castle is made of mud and dried hay as raw materials, and the surrounding high walls serve as protection for the political center. The most beautiful part of the castle is to climb to the highest observation deck, where you can overlook the roofs of the entire city and the surrounding Dasht-e Kavir desert. The ticket is 150,000 Iranian rials, and the overall visit time is 1-2 hours.
