The legend of the name “Trung Trang” Cave

According to the stories of the local people, Cat Ba has long been a beautiful pearl archipelago with countless large and small caves. Therefore, this is considered a “delicious piece of cake” for foreign invaders always looking for opportunities to invade. At that time, to protect the entire territory of the country, Lady Chua Trung Trang - an ancient hero, summoned the young men in the region to the sea to fight the enemy to protect the land.

After successfully repelling the enemy, Lady Chua returned to live in this cave to cultivate and protect the lives of the island's inhabitants. Since then, appreciating Ba Chua's heart, the people in the area named Trung Trang Cave.
