Chaoyang North Tower

Chaoyang North Tower is located in Shuangta District, Chaoyang City, Liaoning Province, People's Republic of China, named after the tower's northernmost location among the three towers in Chaoyang City in the early years. The tower lacks explicit documentation in the historical record. During the extensive maintenance from 1984 to 1992, the archaeological team discovered the rammed earth tower foundations of the Sixteen Kingdoms period, the Northern Wei Dynasty, the Sui Dynasty, the Tang Dynasty and the Liao Dynasty beneath the Chaoyang North Tower during construction. The base of the tower was eventually combined with historical materials and other archaeological findings to discover that the existing tower was built in the Tang Dynasty and rebuilt in the Liao Dynasty. The tower is also known as the "Five Ages Pagoda" or "Pagoda of Five Ages with One Body" because the base of the tower beneath it spans five eras. The sōrin of the tower is a thirteen-story brick tower with dense eaves, 42.6 meters high, consisting of a pedestal, a semi-pedestal, a towed body, dense eaves, and a tower brake. There is a tower door on the south side of the tower, through which one can enter the heart of the tower. The highest point of the tower's core chamber can reach 27 meters, and there is an underground Palace directly below it and a celestial Palace directly above it in which two Shakyamuni relics were unearthed in 1988. In 1988, the Chaoyang North Tower was listed as a national key cultural relic protection unit.

History
There are not many explicit records of the Chaoyang North Tower before the Qing Dynasty. During the large-scale maintenance from 1984 to 1992, archaeologists discovered the rammed earth tower foundations of the Sixteen Kingdoms period, the Northern Wei Dynasty, the Sui Dynasty, the Tang Dynasty, and the Liao Dynasty beneath the Chaoyang North Tower during the construction. Only after combining historical materials and other excavated artifacts did archaeologists finally establish the history of the Chaoyang North Pagoda. The tower was built during the Northern Wei Dynasty by order of Empress Dowager Feng, and was first named "Siyan Buddhism ". The building was located on top of the original Palace building sites of the former Yan, Houyan, and Beiyan. In the second year of Renshou of the Sui Dynasty (602), a new "Fanzhuan Temple Pagoda" was built in Yingzhou on the site of the original Siyan Buddha Figure to place the Buddha relics given by Emperor Wen of the Sui Dynasty. During the reign of Emperor Xuanzong Tianbao of the Tang Dynasty, the pagoda was given the name "Kaiyuan Temple Pagoda" and rebuilt again. During the Liao Dynasty, the pagoda was renamed Yanchang Temple Pagoda and restored twice. The restored Chaoyang North Pagoda retains part of the eaves of the original Tang Pagoda.

Structure
Chaoyang North Tower is located in Shuangta District, Chaoyang City, Liaoning Province, People's Republic of China. The tower was so named because there were three towers in Chaoyang City in the early years and were located in the north. The tower is 42.6 meters high, and has a 13-stage square brick tower with a hollow cylinder, from the bottom to the top are the rammed earth foundation, brick pedestal, Xumizuo base, pagoda body, pagoda eaves, and pagoda brakes.

Pedestal and Xumizuo
The rammed earth foundation is similar in length and width, about 100 meters, and 7 meters high, and was originally the site of the Palace of North Yan Longcheng. Above the pedestal is a square pedestal made of green bricks, 26 meters wide and 5.1 meters high, with a distance of 1.3 meters from the outer edge of the pedestal to the Xumizuo. The southwest and southeast corners of the pedestal have corner steps for ascending to the top of the pedestal. The pedestal's east, south, and north directions are built with a corridor. In the corridor, one can see the pillar base stones of Beiyan and the rammed earth or brick pagoda foundations from four eras, including the Northern Wei, Sui, Tang and Liao Dynasties. Because of its special structure, the Chaoyang North Pagoda is also known as the "Pagoda of Five Generations in One House" or "Pagoda of Five Generations in One Body". Pedestals and distal are the Xumizuo, with a height of 4.35 meters and a width of 15.15 meters.

Protection
Due to a previous lightning strike, the top of the eaves of the Chaoyang North Pagoda showed significant damage in the early 1980s. From August 1984 to December 1992, the State Administration of Cultural Heritage of the People's Republic of China allocated funds for a comprehensive repair and inspection of the Chaoyang North Tower, and after the maintenance project, the Chaoyang North Tower was restored to its original appearance. In 1990, a special museum of Buddhist culture was established based on the Chaoyang North Pagoda, namely the Chaoyang North Pagoda Museum. In 1988, the North Tower of Chaoyang was listed as a national key cultural relic protection unit. In 2003, the Chaoyang North Tower was renovated again to match the transformation of the old city of Chaoyang. In 2004, the North Tower Plaza centred on the Chaoyang North Tower, was completed and opened to the public. In the same year, the new site of the Chaoyang Beita Museum was completed and officially opened to the public in 2006.
