Chaoyang North Tower () is located in Shuangta District, Chaoyang City, Liaoning Province, People's Republic of China. It is named after the tower's northernmost location among the three towers in Chaoyang in the early years. The tower lacks explicit documentation in historical records. During 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.杜斌. 朝阳北塔——五世同堂宝塔. 佛学研究. 2007: 208–215. The tower was built during the Northern Wei Dynasty by order of Empress Dowager Feng, and was first named "Siyan Buddhism".Buddha" is an alias for "Pagoda", also known as "Futu".《魏书·后妃列传》"文成文明皇后冯氏, 长乐信都人也.......太后立文宣王庙于长安, 又立思燕佛图于龙城, 皆刊石立碑." The building was located on top of the original Palace building sites of the former Yan, Houyan, and Beiyan.The specific location is determined by the pillar foundation stones from the Sixteen Kingdoms period and the pagoda base from the Beiyan period discovered between 1984 and 1992. 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.The construction purpose and construction time of the pagoda are determined by the records of the Buddhist relics found in Tiangong and the inscription bricks found in the Liao Dynasty. During the reign of Emperor Xuanzong Tianbao of the Tang Dynasty, the pagoda was given the name "Kaiyuan Temple Pagoda" and rebuilt again.Due to the perennial wars with the Khitan people here, the time for the tower to be built according to historical data is only during the reign of Emperor Xuanzong of the Tang Dynasty. According to the inscriptions found on the building components during the archaeological discovery and maintenance period, as well as the remnants of the Tang Dynasty stele in the foundation, it can be determined that the tower was built in the Tianbao period. 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.Determined by the inscription brick found during the maintenance process, which reads "Re-burial of the relic on April 8, 12th year of Chongxi under the "Great Pagoda of Yanchang Temple", and part of the eaves of the tower are covered with paintings, the outermost two floors were painted in the Liao Dynasty, while the third floor was painted in the Tang Dynasty; in addition, the inscription on the Stone Scripture Building in the underground palace also records that it was rebuilt in the thirteenth year of Chongxi.

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".

Eaves and brakes The eaves portion of the tower has 13 floors in total, the first to the eleventh floors having been transformed from the eaves of the fourth to the fourteenth floors of the Sui Tang Pagoda, and the twelfth and thirteenth floors having been both reconstructed in the Liao Dynasty. The first floor is an imitation wood, brick arch with a large eave which is 1.64 meters high and 1.96 meters out. From the second story onwards, the eaves of the tower are gradually divided. Above the eaves, part of the tower is the tower brake. The base of this pagoda is a brick octagonal rosette. The rosette is surmounted by a girdle and a green glass glazed rosette with an overlapping bowl above the rosette.

The middle of the twelfth floor of the tower eaves, above the top of the tower's core chamber, is the Heavenly Palace that can be divided into three parts: the doorway, the canal, and the Palace room, of which the doorway opening to the south is 1.03 meters long, 1.43 meters wide and 1.72 meters high, and the canal on the north side of the doorway which is 1.2 meters long from north to south, 1.8 meters wide from east to west and 1.72 meters high. The canal's northern end is a square Palace room, with a side length of 1.39 meters and a height of 1.27 meters. The tops of the Palace rooms and doorways are covered with wooden panels, The tower is above the wooden board, and the interior surfaces were originally painted with white plaster, which has fallen off. The entire celestial Palace shows clear traces of burning after being struck by lightning.梁银景. 朝阳北塔出土泥塑像的渊源及奉安场所探讨. 边疆考古研究. 2008: 259–282.董高,张洪波. 辽宁朝阳北塔天宫地宫清理简报. 文物. 1992-7: 1–28, 97–103.
