The Nariqala fortress is located in the southern Sololaki Mountains of Tbilisi Old Town and is an important line of defense around Tbilisi. The fortress was built in the 4th century AD, and most of the buildings that tourists see now were rebuilt after the 17th century. In 1827, the explosion of the gunpowder warehouse stationed in the Russian army caused serious damage to the fortress. The church of St. Nicholas in the fortress was also destroyed. The current building was rebuilt after the collapse of the Soviet Union. At the top of the hill you can see the fortress and the statue of the mother of Georgia, and at night you can overlook the charming night lights of the city.
