Lhasa is noted for its historic buildings and structures related to Tibetan Buddhism. Several major architectural works have been included as UNESCO's World Heritage Sites.

Potala Palace

The Potala Palace, named after Mount Potala, the abode of Chenresig or Avalokiteśvara,Stein, R. A. Tibetan Civilization (1962). Translated into English with minor revisions by the author. 1st English edition by Faber & Faber, London (1972). Reprint: Stanford University Press (1972), p. 84 was the chief residence of the Dalai Lama. After the 14th Dalai Lama fled to India during the 1959 Tibetan uprising, the government converted the palace into a museum.

The building measures 400 metres east-west and 350 metres north-south, with sloping stone walls averaging 3 m. thick, and 5 m. (more than 16 ft) thick at the base, and with copper poured into the foundations to help proof it against earthquakes.Booz, Elisabeth B. (1986). Tibet, pp. 62–63. Passport Books, Hong Kong. Thirteen stories of buildings – containing over 1,000 rooms, 10,000 shrines and about 200,000 statues – soar 117 metres (384 ft) on top of Marpo Ri, the "Red Hill", rising more than 300 m (about 1,000 ft) in total above the valley floor.Buckley, Michael and Strausss, Robert. Tibet: a travel survival kit, p. 131. Lonely Planet. South Yarra, Vic., Australia. . Tradition has it that the three main hills of Lhasa represent the "Three Protectors of Tibet." Chokpori, just to the south of the Potala, is the soul-mountain (bla-ri) of Vajrapani, Pongwari that of Manjushri, and Marpori, the hill on which the Potala stands, represents Chenresig or Avalokiteshvara.Stein, R. A. (1972). Tibetan Civilization, p. 228. Translated by J. E. Stapleton Driver. Stanford University Press, Stanford, California. (cloth); (paper).

The site was used as a meditation retreat by King Songtsen Gampo, who in 637 built the first palace there in order to greet his bride Princess Wencheng of the Tang dynasty of China. Lozang Gyatso, the Great Fifth Dalai Lama, started the construction of the Potala Palace in 1645Laird, Thomas. (2006). The Story of Tibet: Conversations with the Dalai Lama, pp. 175. Grove Press, New York. . after one of his spiritual advisers, Konchog Chophel (d. 1646), pointed out that the site was ideal as a seat of government, situated as it is between Drepung and Sera monasteries and the old city of Lhasa.Karmay, Samten C. (2005). "The Great Fifth", p. 1. Downloaded as a pdf file on December 16, 2007 from: Construction lasted until 1694,Stein, R. A. Tibetan Civilization (1962). Translated into English with minor revisions by the author. 1st English edition by Faber & Faber, London (1972). Reprint: Stanford University Press (1972), p. 84. some twelve years after his death.

The palace underwent restoration works between 1989 and 1994, costing RMB55 million (US$6.875 million) and was inscribed to the UNESCO World Heritage List in 1994. In 2000 and 2001, Jokhang Temple and Norbulingka were added to the list as extensions to the sites. Rapid modernisation has been a concern for UNESCO, however, which expressed concern over the building of modern structures immediately around the palace which threaten the palace's unique atmosphere. The Chinese government responded by enacting a rule barring the building of any structure taller than 21 metres in the area.

The White Palace or Potrang Karpo is the part of the Potala Palace that makes up the living quarters of the Dalai Lama. The first White Palace was built during the lifetime of the Fifth Dalai Lama and he and his government moved into it in 1649. It then was extended to its size today by the thirteenth Dalai Lama in the early twentieth century. The palace was for secular uses and contained the living quarters, offices, the seminary and the printing house. A central, yellow-painted courtyard known as a Deyangshar separates the living quarters of the Lama and his monks with the Red Palace, the other side of the sacred Potala, which is completely devoted to religious study and prayer. It contains the sacred gold stupas—the tombs of eight Dalai Lamas—the monks' assembly hall, numerous chapels and shrines, and libraries for the important Buddhist scriptures, the Kangyur in 108 volumes and the Tengyur with 225.

The Red Palace or Potrang Marpo is part of the Potala Palace that is completely devoted to religious study and Buddhist prayer. It consists of a complicated layout of many different halls, chapels and libraries on many different levels with a complex array of smaller galleries and winding passages: The main central hall of the Red Palace is the Great West Hall which consists of four great chapels that proclaim the glory and power of the builder of the Potala, the Fifth Dalai Lama. The hall is noted for its fine murals reminiscent of Persian miniatures, depicting events in the fifth Dalai Lama's life. The famous scene of his visit to Emperor Shun Zhi in Beijing is located on the east wall outside the entrance. Special cloth from Bhutan wraps the Hall's numerous columns and pillars. On the north side of this hall in the Red Palace is the holiest shrine of the Potala. A large blue and gold inscription over the door was written by the 19th century Tongzhi Emperor of China. proclaiming Buddhism a Blessed Field of Wonderful Fruit. On the floor below, a low, dark passage leads into the Dharma Cave where Songtsen Gampo is believed to have studied Buddhism. In the holy cave are images of Songtsen Gampo, his wives, his chief minister and Sambhota, the scholar who developed Tibetan writing in the company of his many divinities.

The tomb of the 13th Dalai Lama is located west of the Great West Hall and it can only be reached from an upper floor and with the company of a monk or a guide of the Potala. Built in 1933, the giant stupa contains priceless jewels and one ton of solid gold. It is 14 metres (46 ft) high. Devotional offerings include elephant tusks from India, porcelain lions and vases and a pagoda made from over 200,000 pearls. Elaborate murals in traditional Tibetan styles depict many events of the life of the Thirteenth Dalai Lama during the early 20th century.

Norbulingka

The Norbulingka palace and surrounding park is situated in the west side of Lhasa, a short distance to the southwest of Potala Palace and with an area of around , it is considered to be the largest man made garden in Tibet. It was built from 1755.Tibet (1986), p.71 and served as the traditional summer residence of the successive Dalai Lamas until the 14th's self-imposed exile. Norbulingka was declared a ‘National Important Cultural Relic Unit”, in 1988 by the State council. In 2001, the Central Committee of the Chinese Government in its 4th Tibet Session resolved to restore the complex to its original glory. Grant funds to the extent of 67.4 million Yuan (US$8.14 million) were sanctioned in 2002 by the Central Government for the restoration works; the restoration works taken up from 2003 mainly covered the Kelsang Phodron Palace, the Kashak Cabinet offices and many other structures.

The summer residence of the Dalai Lama is now a tourist attraction. The palace has a large collection of Italian chandeliers, Ajanta frescoes, Tibetan carpets and many other artifacts. Murals of Buddha and the 5th Dalai Lama are seen in some rooms. The 14th Dalai Lama’s (who fled from Tibet and took asylum in India) meditation room, bedroom, conference room and bathroom are part of the display explained to the tourists.Seth, pp.140–141

The Sho Dun Festival (popularly known as the "yogurt festival") is an annual festival held at Norbulingka during the seventh Tibetan month in the first seven days of the Full Moon period, which corresponds to dates in July/August according to the Gregorian calendar. The week-long festivities are marked by eating and drinking, with Ache Lhamo, the Tibetan opera performances as the highlight, held in the park and other venues in the city. On this occasion yak races are a special attraction held in the Lhasa stadium. During this festival, famed opera troupes from different regions of Tibet perform at the Narubulingka grounds; the first opera troupe was founded in the 15th century by Tangtong Gyelpo (considered the Leonardo da Vinci of Tibet). Over the centuries other opera formats of the 'White Masked Sect' and the "innovative" 'Black Masked Sect' added to the repertoire, and all these forms and subsequent innovations are enacted at the Sho Dun festival.

Barkhor

The Barkhor is an area of narrow streets and a public square in the old part of the city located around Jokhang Temple and was the most popular devotional circumambulation for pilgrims and locals. The walk was about one kilometre long and encircled the entire Jokhang, the former seat of the State Oracle in Lhasa called the Muru Nyingba Monastery, and a number of nobles' houses including Tromzikhang and Jamkhang. There were four large incense burners (sangkangs) in the four cardinal directions, with incense burning constantly, to please the gods protecting the Jokhang.Dowman, Keith (1998). The Power-Places of Central Tibet: The Pilgrim's Guide, pp. 40–41. Routledge & Kegan Paul, London and New York. . Most of the old streets and buildings have been demolished in recent times and replaced with wider streets and new buildings. Some buildings in the Barkhor were damaged in the 2008 unrest.

Jokhang

The Jokhang is located on Barkhor Square in the old town section of Lhasa. It was founded around 642 during the reign of king Songtsen Gampo (605?–650 CE) to celebrate his marriage with Chinese Tang dynasty Princess Wencheng.Norbu and Turnbull 1969, p. 143 For most Tibetans it is the most sacred and important temple in Tibet. It is in some regards pan-sectarian, but is presently controlled by the Gelug school. Along with the Potala Palace, it is probably the most popular tourist attraction in Lhasa. It is part of the UNESCO World Heritage Site "Historic Ensemble of the Potala Palace," and a spiritual centre of Lhasa. This temple has remained a key center of Buddhist pilgrimage for centuries. The circumambulation route is known as the "kora" in Tibetan and is marked by four large stone incense burners placed at the corners of the temple complex. After circumambulating the exterior, pilgrims make their way to the main hall of the temple which houses the Jowo Shakyamuni Buddha statue, perhaps the single most venerated object in Tibetan Buddhism. There are also famous statues of Chenresig, Padmasambhava and King Songtsen Gampo and his two foreign brides, Princess Wencheng (niece of Emperor Taizong of Tang) and Princess Bhrikuti of Nepal.

Jokhang was sacked several times by the Mongols, but the building survived. In the past several centuries the temple complex was expanded and now covers an area of about 25,000 sq. meters

The Jokhang temple is a four-story construction, with roofs covered with gilded bronze tiles. The architectural style is based on the Indian vihara design, and was later extended resulting in a blend of Nepalese and Tang dynasty styles. The rooftop statues of two golden deer flanking a Dharma wheel is iconic. Jokhang's interior is a dark and atmospheric labyrinth of chapels dedicated to various gods and bodhisattvas, illuminated by votive candles and thick with the smoke of incense. Although some of the temple has been rebuilt, original elements remain: the wooden beams and rafters have been shown by carbon dating to be original; the Newari door frames, columns and finials date from the 7th and 8th centuries.
