The Summer Palace occupies 290 hectares in the northwestern Haidian District of Beijing, positioned 15 kilometers from the center of the old walled city. Construction of the current complex began in 1750 under Emperor Qianlong and concluded in 1764, though the site had functioned as an imperial garden since the Jin Dynasty in the 12th century. The园明园 (Yuanmingyuan) or Old Summer Palace originally stood adjacent to this site until British and French forces destroyed it in 1860 during the Second Opium War. Empress Dowager Cixi diverted funds allocated for naval modernization to rebuild the current Summer Palace between 1886 and 1895, spending an estimated 30 million taels of silver on reconstruction. The UNESCO World Heritage designation arrived in 1998, citing the palace as a masterpiece of Chinese landscape garden design.
Kunming Lake comprises three-quarters of the total palace area, measuring 2.2 square kilometers with a maximum depth of 3 meters. Qianlong ordered the lake expanded from the existing Wengshan Pond to replicate West Lake in Hangzhou, though the dimensions differ substantially. Workers excavated 3.5 million cubic meters of earth to create the current lake basin, using the removed soil to raise Longevity Hill 60 meters above the lake surface. Three artificial islands divide the water surface: Nanhu Island connected to shore by the Seventeen-Arch Bridge, and two smaller unnamed islands accessible only by boat. The Seventeen-Arch Bridge extends 150 meters with 544 carved stone lions on the balustrades, each lion differing in posture and expression. The bridge replicates the design principles of the Marco Polo Bridge 30 kilometers southwest, though built 500 years later.
Longevity Hill rises as the vertical anchor of the complex, its southern slope terraced with religious and ceremonial structures arranged along a central north-south axis. The Four Great Regions architectural ensemble occupies the summit, representing Buddhist cosmology with structures in Han, Tibetan, Mongolian, and Islamic architectural styles. The Tower of Buddhist Incense stands 41 meters tall at the hill's center, originally built as an nine-story pagoda before Qianlong ordered it demolished and replaced with the current octagonal structure during construction. The tower foundation required 8,000 cubic meters of rammed earth and granite blocks anchored directly into bedrock. Visitors climb 120 steps from the Cloud-Dispelling Hall to reach the tower base, which contains bronze Buddhist statuary cast in 1750. The Wisdom Sea Hall crowns the summit behind the tower, its facade covered with thousands of green and yellow glazed tiles forming Buddhist imagery.
The Long Corridor extends 728 meters along the northern shore of Kunming Lake, connecting the eastern palace residential quarters to the marble boat at the western terminus. The corridor contains 273 sections divided by crossbeams, with over 14,000 painted panels on the ceiling beams and crossbeams. Artisans painted scenes from Chinese literature including Romance of the Three Kingdoms, Journey to the West, and Dream of the Red Chamber, whose author Cao Xueqin lived in Beijing and set portions of his novel in gardens resembling these imperial landscapes. Each painting measures approximately 30 by 40 centimeters, with no two panels identical. The corridor survived the 1860 destruction because foreign troops concentrated their burning on palace structures rather than lakeside walkways. Cixi commissioned complete repainting of damaged sections during the 1880s reconstruction, though art historians note stylistic differences between pre-1860 and post-1886 panels based on pigment composition and brushwork technique.
The Garden of Virtue and Harmony contains a three-story opera theater completed in 1891, measuring 21 meters in height with a stage area of 685 square meters. The stage incorporated trap doors for appearances and disappearances, wells for water effects during naval battle scenes, and concealed rooms above and below the visible stage for supernatural entrances. Cixi watched performances from the Hall of Fostering Happiness directly opposite, seated on a throne positioned 15 meters from the stage. Court records document 267 opera performances between 1892 and 1908, with some productions employing over 100 performers simultaneously. The theater abandoned traditional outdoor stage design for this enclosed structure because Cixi preferred year-round performances regardless of weather.
The Marble Boat rests permanently at the western end of the Long Corridor, its hull carved from Fangshan limestone and the two-story superstructure built from painted wood. Qianlong's original 1755 wooden-hulled boat was destroyed in 1860 and replaced during Cixi's reconstruction with the current 36-meter stone and wood hybrid. The upper deck contained stained glass windows imported through Tianjin, representing one of the first architectural uses of European glass techniques in Chinese imperial construction. The boat served as a lakeside pavilion for viewing moon reflections and drinking tea rather than for navigation, though the symbolism of an immobile boat built with naval funds during Japan's military expansion drew contemporary criticism from reform officials.
The Hall of Benevolence and Longevity functioned as the primary audience hall where Cixi conducted state business after 1898, following her effective imprisonment of Emperor Guangxu in a complex of buildings on a lake island. The hall contains a hardwood throne carved during the Qianlong period, with bronzes in the courtyard including a qilin cast in the Ming Dynasty and a pair of incense burners dated to 1750. Cixi met foreign diplomats in this hall after 1902, marking a departure from Qing protocol that previously restricted foreigners from entering operational palace spaces. The building faces south across a courtyard to Kunming Lake, following feng shui principles requiring administrative buildings to orient toward water sources representing wealth and toward south-facing solar exposure.
The Suzhou Street commercial area along the Back Lakes recreated a Jiangnan water town with shops, teahouses, and bridges, though what visitors see today represents a 1990s reconstruction of structures demolished in 1860. Historical records describe the original street as containing 64 shops operated by palace eunuchs and maids performing as merchants while the emperor and his entourage role-played as customers. Archaeological excavations in 1986 located original shop foundations and stone bridges 80 centimeters below the current ground level, providing dimensional references for the reconstruction. The rebuilt street extends 300 meters with buildings in Qing Dynasty commercial architecture, though modern safety codes required modifications to stairs and railings not present in 18th-century originals.
Preservation challenges center on the wooden Long Corridor, which requires constant maintenance due to humidity from the adjacent lake. Beijing's average annual relative humidity of 56 percent creates conditions for wood decay and paint deterioration, necessitating section-by-section restoration on a rotating schedule. Conservators repaint approximately 2,000 panels annually, matching pigments to original mineral-based paints that used azurite for blues, malachite for greens, and cinnabar for reds. The State Administration of Cultural Heritage allocated 300 million yuan between 2003 and 2008 for comprehensive structural repairs to buildings damaged during the Cultural Revolution when the site remained open but unmaintained. Current visitor capacity limits reach 80,000 people daily during peak seasons, with October Golden Week periods regularly approaching this threshold.
