Zhejiang Pinghu Tianfei Palace Battery

Tianfei Palace Battery was built in the 56th year of the Kangxi period of the Qing dynasty (1717). It faces south and consists of four fan-shaped batteries, which are arranged in a fan shape. The batteries are partially damaged, with the top damaged. They are made of lime, glutinous rice, sand, and alum, and cover an area of about 400 square meters. The middle two batteries were bombed by Japanese aircraft in October of the 26th year of the Republic of China (1937), and the top collapsed. The north and south batteries are still intact and basically maintain their original appearance. The outer edge of the battery is built with rectangular stones, with a width of 1.65–1.8 meters, a length of 5.63 meters, and a height of 5 meters above the beach. There are three remaining iron cannons, which are placed in the fan-shaped battery facing south. The middle cannon originally had a mechanical device, with a total weight of about 10.2 tons. The cannon is engraved with the words "Made in the 10th year of the Guangxu period" and "Jiangnan Manufacturing Bureau". The right cannon weighs about 2.9 tons, and the cannon is engraved with the words "52-2-21835, East *". The left cannon weighs about 3.7 tons, and the cannon is engraved with the words "1845·* Fire". It is a national key cultural relic protection unit.
