The Former Site of Jinan Swastika Society, also known as Jinan Daoyuan or the Mother Temple of the World Red Swastika Society, is a grand architectural complex blending palace and temple styles, located at 51 Shangxin Street, Shizhong District, Jinan. This site represents a rare and classic example of modern Chinese architecture that utilizes reinforced concrete to imitate traditional Ming and Qing dynasty palatial structures.

The construction of the site began in 1934 and was completed in 1942. Its predecessor was the "Daoyuan," a folk religious organization founded in Jinan in 1921 by Du Bingyin and others. In 1922, the Daoyuan established the charitable organization "World Red Swastika Society," and because Jinan was its birthplace, this Daoyuan became known as the "Mother Temple." The Red Swastika Society aimed to "promote world peace and relieve disasters," advocating the unity of the five major religions: Confucianism, Buddhism, Taoism, Islam, and Christianity. By 1940, the organization had established over 400 branches throughout China. After the liberation of Jinan in 1948, the complex was taken over by the Shandong Ancient Cultural Relics Management Committee. It subsequently served as the exhibition hall for the Shandong Provincial Museum and later housed the offices of the Shandong Provincial Cultural Relics Bureau.

Architecturally, the complex is a rare example of modern Chinese architecture that uses reinforced concrete to replicate traditional Ming and Qing palatial timber structures. The design was led by Xiao Yijiu, a student of the renowned architect Liang Sicheng, along with Zhu Zhaoxue and Yu Gaomin. The construction was carried out by Beijing’s ancient building contractors, Hengmaoxing and Guanghexing Construction Factory. The complex faces south, covering an area of approximately 14,000 square meters, with a building area of about 6,000 square meters. Its overall design follows the layout principles of traditional Chinese palaces, featuring four courtyards symmetrically arranged along a central axis. From south to north, the main buildings include the screen wall, main gate, front hall, mother hall (main hall), Chenguang Pavilion, and rear living quarters, flanked by side rooms, corridors, side gates, and octagonal pavilions.

The most distinctive feature of the complex is its innovative use of reinforced concrete to imitate traditional palatial wooden structures while skillfully integrating both traditional Chinese and modern Western decorative elements. The roof, dougong brackets, and painted decorations adhere strictly to the official architectural practices of the Ming and Qing dynasties, while the interior spaces, doors, windows, and decorative finishes draw inspiration from Western architectural design techniques.

Key structures within the complex include the grand screen wall, the largest of its kind among Jinan’s historical buildings. Its base features a stone-carved Sumeru pedestal, and the wall is adorned with high-relief glazed carvings of potted landscapes inscribed with the characters for "auspiciousness." The Chenguang Pavilion, designed with twelve sides, symbolizes the "twelve hours of the day and twelve months of the year," reflecting traditional Chinese philosophical concepts. The painted decorations throughout the complex are exquisitely crafted, with precise lines and delicate brushwork. The main halls often feature "Xuanzi-style" painted decorations under their eaves, while secondary structures such as corridors and side rooms employ "Suzhou-style" painted decorations.

In terms of protection and current status, the site was designated as a Shandong Provincial Cultural Relics Protection Unit in 1992 and was elevated to a National Key Cultural Relics Protection Unit by the State Council in 2006. It was included in the third batch of "China’s 20th Century Architectural Heritage" in 2018. Since 2022, the Shandong Provincial Institute of Ancient Architecture Protection has undertaken comprehensive renovation and conservation work on the complex. In April 2025, with approval from the Shandong Provincial Party Committee Office for Institutional Establishment, the complex was designated as the Shandong Ancient Architecture Museum, the province’s first specialized museum dedicated to architectural heritage. Its future mission is to promote the protection of historical urban landscapes and revitalize the old city. During the National Day holiday in 2025, the museum held an "Open Day" event, though only the exterior of the buildings was accessible to visitors due to ongoing restoration work.
