Lungshan Temple was first built in 1653 (the 10th year of Emperor Shunzhi's reign of the Qing Dynasty) by Zhao Shan the Master Monk by moving an Avalokitesvara bronze statue of the Tang Dynasty to Lugang from Longshan Temple in the Quan Prefecture, thus beginning the construction of the temple. It was subsequently repaired, maintained and rebuilt many times. The layout and the structural pattern of the whole temple is the image of Wenling Longshan Temple. It is said the skilful craftsmen were invited from Fujian, Guangdong and other provinces to design and construct the temple. There are 99 doors altogether. The temple is very magnificent. The stone drums, stone columns, stone doors, stone walls and stone balustrades are all simple and unsophisticated. Especially the dragon columns are delicately carved, lining up in three rows one after another in different style but exquisitely worked out with the conspicuous relief beards and brows in vivid posture, They form an art treasure of stone carving in Taiwan winning the good reputation of "Taiwan Art Hall". In the hall proper, Avalokitesvara, Bodhisattva are enshrined; around them are 18 arhats, each of which is lifelike. At the right wall corner, there is a big bell, standing two meters high with a diameter of 1.2 meters, which weighs about five hundred kilograms. It is the biggest bronze bell ever seen in Taiwan temples at present. According to records, this big Bell was cast by several craftsmen from Ningbo, Zhejiang Province in 1859 (the 9th year of Emperor Xianfeng's reign of the Wing Dynasty) ringing loud and clear which can be heard far away. It is known as "Dragon Hill Morning Bell".

In the front courtyard of the temple a meridian gate platform was built, known as the "Grand Theatre" and the sunk panels of the theatre is known as the Eight Diagrams Ceiling. It is made of exquisite wood carving matched with the well-designed tenon without a single iron nail. The relief sculptures on the sunk panels look extremely resplendent with colored drawings. The roofs of the halls imitate the swallow tail sticking upward. The vertical ridges of the roofs are painted with phoenix decoration and red tiles and walls, purple columns and red-lacquered doors all give forth to a riot to color. The open floor surface of the temple is neatly paved with big granite slabs. The outer low enclosure encircling the temple serves as the hilly wall. It is decorated with pack elephant sculpture. The construction of the hilly gates is extremely unique of its kind and 5 gates are formed by 3 independent roofs. The roofs are formed by double eaves gutters proportionally harmonized with outstanding style. Being maintained and renovated by various craftsmen in the Qing Dynasty, the Lungshan Temple has preserved the style and features of temple architecture in the early period of the Qing Dynasty.
