Bagan sits on the eastern bank of the Irrawaddy River in the Mandalay Region, occupying approximately 104 square kilometers of arid plain. Between the ninth and thirteenth centuries, rulers of the Pagan Kingdom constructed more than 10,000 Buddhist temples, pagodas, and monasteries across this zone. Approximately 2,200 structures remain standing today. The Bagan Archaeological Zone received UNESCO World Heritage designation in 2019 after decades of reconstruction efforts and documentation. The site divides into three primary areas: Old Bagan contains the densest concentration of major temples and was cleared of residential occupation in 1990 when the military government relocated roughly 5,000 residents to New Bagan two kilometers south. Nyaung U, three kilometers northeast, functions as the main commercial town with hotels, restaurants, and the nearest airport. The Irrawaddy riverbank defines the western boundary, while scrubland and agricultural plots extend eastward to the Tuyin Taung hills.
King Anawrahta unified the region in 1044 and established Bagan as capital of the first Burmese empire. His conversion to Theravada Buddhism under the influence of Mon monk Shin Arahan initiated the temple construction era that continued for 250 years. Anawrahta conquered the Mon capital of Thaton in 1057, bringing back Buddhist texts, artisans, and the tooth relic tradition that shaped Bagan's religious architecture. His successor Kyansittha completed the Ananda Temple in 1105, establishing architectural standards that subsequent rulers followed. The building boom peaked under King Narapatisithu between 1174 and 1211, when the Dhammayangyi and Sulamani temples rose above the plain. Construction declined after 1287 when Mongol forces under Kublai Khan's grandson invaded, though the city continued as a religious center under Shan and later Toungoo dynasty control. The July 1975 earthquake measuring 6.5 magnitude destroyed or damaged over 2,000 structures, prompting UNESCO technical assistance for restoration work that continues through the present decade.
The Ananda Temple stands 51 meters tall at the center of Old Bagan, its cruciform floor plan and gilded sikhara tower representing the mature Bagan architectural style. Four standing Buddha statues carved from teak measure 9.5 meters each, facing the cardinal directions inside the hollow core. King Kyansittha commissioned the structure after meeting eight monks from India who described the Nandamula cave temple in the Himalayas. The temple compound covers approximately 6,000 square meters, with two receding terraces supporting the central tower. Restoration between 1975 and 1990 replaced damaged stucco and repaired cracks in the masonry walls. The original gilding on the sikhara was renewed in 1990. Murals inside the corridors date to the eighteenth century Konbaung period, painted over earlier twelfth century work. The Ananda Pagoda Festival occurs annually on the full moon of Pyatho (December-January), drawing tens of thousands of pilgrims and merchants to the temple grounds for a week-long market and religious observances.
Dhammayangyi Temple dominates the plain as Bagan's largest structure, measuring 78 meters along each side at its square base. King Narathu ordered its construction around 1170 but was assassinated in 1173 before completion, leaving the inner passages filled with rubble. The temple's distinctive feature is its precision brickwork, with mortar joints so thin that knife blades cannot fit between courses. Legend holds that Narathu ordered workers' hands cut off if they placed bricks imprecisely. Three of four doorways leading to interior sanctums were bricked shut during construction, leaving only the eastern entrance accessible. The central core remains inaccessible due to rubble fill. Four Buddha statues originally occupied the sanctums, but only two survive. The temple's mass absorbed the 1975 earthquake with minimal visible damage compared to hollow structures. UNESCO documentation identifies Dhammayangyi as requiring no active stabilization, though vegetation removal from walls continues annually.
Thatbyinnyu Temple rises 66 meters across five terraces, the tallest temple in Bagan. King Alaungsithu commissioned it around 1144, establishing the vertical emphasis that characterized later Bagan architecture. The name translates to "omniscience," referring to Buddha's complete knowledge. Two stories contain shrines, with the upper level housing a seated Buddha image. The receding terraces create a pyramidal profile visible from Nyaung U five kilometers away. Internal stairways allow access to upper terraces, though the Ministry of Culture closed upper levels to climbing in 2018 to prevent structural stress. The temple sits on elevated ground naturally, adding another 10 meters to its prominence. Glazed tiles decorated the sikhara originally, with traces remaining on the northern face. The 1975 earthquake cracked the eastern wall, requiring steel reinforcement installed between 1976 and 1978. Adjacent to the temple, the Thatbyinnyu Pahto Library once stored palm-leaf manuscripts, though the collection was dispersed during the Konbaung period.
Shwesandaw Pagoda offers one of five official sunrise viewing platforms approved by Myanmar authorities after the 2018 climbing ban. Built by King Anawrahta in 1057 to house hair relics of Buddha brought from Bago, it stands 50 meters tall on five square terraces. Steep stairways ascend the terraces on all four sides, with iron railings installed in 1995 for visitor safety. The cylindrical stupa at the summit was rebuilt in 1990 after earthquake damage compromised the original brickwork. From the fourth terrace at approximately 40 meters elevation, views extend across the central plain encompassing roughly 20 square kilometers of temple landscape. The Ministry of Religious Affairs and Culture limits daily visitors to 300 persons during sunrise hours between November and February peak season. The pagoda stands 1.5 kilometers southwest of Ananda Temple, reachable by paved road or dirt paths through temple complexes.
Sulamani Temple exhibits late Bagan architectural refinement, constructed in 1183 under King Narapatisithu. The name means "crowning jewel" or "small ruby." Its two stories contain interior corridors with original twelfth century murals depicting Jataka tales across approximately 400 square meters of wall surface. These frescoes represent the best-preserved painting cycles in Bagan, protected from weather by the double-wall construction. The temple rises from two receding terraces to a central sikhara tower. Four smaller stupas at the corners of the upper terrace create a five-spire arrangement. The 1975 earthquake toppled these corner stupas and cracked the central tower, requiring extensive reconstruction between 1994 and 1998 using traditional materials and techniques. UNESCO technical advisors documented the original structure through photogrammetry before reconstruction began. The interior Buddha images were regilded during this period. Sulamani sits on the eastern edge of the temple zone near Myinkaba village, approximately four kilometers south of Ananda Temple.
Htilominlo Temple was commissioned by King Htilominlo in 1218, one of the last major temples built before Bagan's decline. The name derives from the king's title, meaning "blessing of the three worlds." Rising 46 meters across three terraces, it demonstrates the vertical emphasis of late Bagan architecture. Glazed sandstone decorations once covered much of the exterior, with remnants surviving on the western face showing green and yellow tile work. Four Buddha images occupy ground floor shrines facing cardinal directions. Murals in the interior corridors date to multiple periods, with thirteenth century originals overlaid by fifteenth and nineteenth century repainting. The temple suffered severe damage in the 1975 earthquake when the upper sikhara collapsed entirely. Reconstruction using original bricks took place between 1980 and 1983. The Archaeological Department installed metal grilles over windows in 2005 to prevent bat colonies from nesting inside and damaging murals with guano. Htilominlo stands immediately north of Old Bagan, beside the road to Nyaung U.
