Fongshan Longshan Temple mainly worships Guanyin (Avalokitesvara). It was founded in the Qing Qianlong Period, and its artistic value is equal to the Longshan Temples in Monga and Lugang.
Fongshan Longshan Temple went through several renovations, yet research proves that its axis structure is almost perfectly preserved in Qing Dynasty Qianlong and Jiaqing era styles, making the building precious to local history. Renovations after the war involved Tainan's sculpting master Ye Hao. The Fongshan Longshan Temple not only retains a layout original to the Qing Dynasty, but also features exquisite details and ingenuity. The wooden, engraved window at the front of the main hall is one of the main characteristics of Longshan Temple, and is essential to its artistic presentation. Carved windows on each side of the middle door features a top panel with character play carved in relief, and a main body featuring a group of cranes. A hidden couplet can be found on the left and right panels. The Fongshan Longshan Temple is intricately designed and retains its traditional craftsmanship, holding great significance in both historical and artistic value.
