A strong fortress that stretches a few meters along the Gilgilchay River, descends into the Caspian Sea and rises to the mountains.

Inside the castle were found several remains of fortresses.

In the province of Guba, the village of Khazra (Holy) is located near the border of Azerbaijan with Dagestan. the Sheikh Junaid is a direct descendant of Sheikh Safi ad-din Yakub, the founder of the Safavid Iranian dynasty. Junaid's grandson built a magnificent tomb over Shah Tahmasib's grave. The walls of the mausoleum reach half a meter height and are covered with blue and black-and-violet glass tiles.

Chirag Castle

Near the high mountains, the ruins of Chirag-Kala Castle, the main point of the defense system of Gilgilchay Castle, are preserved. The north-east fortress walls are protected by a deep rock. The ruins of these towers are protected to this day. Towers were used to warn the danger ("Chrig-Kala" means "tower lamp"). At the tops of the towers, the fire was seen from a few kilometers away. The Chirag-Kala fortress was a kind of 'informant' and the largest alert system among other medieval towers. The path to the Chirag Castle is quite long: It is advisable to be prepared beforehand for the journey to the castle as it's taking much time.

Red settlement 

Fatali khan, the most famous of the rulers of the Guba khanate, tried to unite all khanates of Azerbaijan under his leadership. He subdued all northeastern Azerbaijan from Derbent to Lankaran. At that time, the Jews were invited to settle in Guba, on the left bank of the Kudyalchai. This settlement, formerly called the Jewish Slobodas, has been called the Red Settlement since 1926. The Red Town is a very famous Jewish village with two active synagogues, including the Great Synagogue. Its convenient existence is often proved as evidence of Azerbaijan's religious tolerance.
