Sakya's map of sacred sites shows, like its history, a rare double character: on one side are the monasteries with pale-earth walls in the valleys of Upper Tsang, weighty and reserved; on the other it extends to the southern foothills of the Himalayas in Nepal, and once even reached the court of the Yuan capital at Dadu.

These seats of dharma share one thing: they are mostly famed for their libraries. Sakya is a school of scholars, so its monasteries are also like libraries. The wall of scriptures at Sakya Monastery, the canon of Ngor Monastery, the murals in the Mustang valleys — all silently tell of this school's temperament.

The following seats of dharma are where Sakya's lineage took root on the snowy plateau; each has a dedicated article.

• Sakya Monastery (Sakya Monastery) — built in 1073, divided into South and North monasteries; the root seat of Sakya, famed for its wall of scriptures and Yuan-era architecture.
• Ngor Monastery (Ngor Monastery, built 1429) — the source-monastery of the Ngor Branch, renowned for the Vajrakīla ceremony and maṇḍala rituals.
• The Tshar Branch seats — famed for the preservation of tantric oral instructions, scattered across Upper Tsang.
• Samye (Samye) — the first monastery on the Tibetan plateau, historically long administered by Sakya, a sacred site honored by all schools.
• Mustang (Mustang, Nepal) — a Tibetan-cultural enclave on the southern foothills of the Himalayas, where Sakya's influence runs deep and its monasteries and murals are well preserved.
• Nartang (Nartang) — an ancient monastery in Upper Tsang, famous for its woodblock printing plates and printing house, closely tied to Sakya.

Each opens into a complete illustrated article:

Sakya Monastery sits in Sakya County, Shigatse, at about 4,300 meters above sea level, divided into South and North parts:

The North Monastery is the earliest seat, built by Khön Könchog Gyalpo in 1073 on the hillside. Built against the mountain, with halls scattered, it was Sakya's early center of study and practice. After the mid-twentieth century the North Monastery suffered severe damage; today it is mostly ruins, with only a few structures remaining.

The South Monastery was built in 1268 under Pakpa's direction, on the plain south of the Phun Chhu river. It is a castle-like structure — a square compound, high thick walls, watchtowers at the four corners, its outer walls painted with vertical stripes in red, white, and blue (or black), whence the Han name "Variegated School." This form is extremely rare among Tibetan monasteries, more like a fortress than a temple.

The great assembly hall of the South Monastery is its most stunning space: along the wall stands an entire wall of scriptures, layer upon layer of tens of thousands of volumes of Tibetan canon, said to number as many as eighty-four thousand. This wall is considered the world's largest "bookshelf," and the most direct proof of Sakya as a school of scholars.

The North and South monasteries together are like two sides of Sakya's character: one a practitioner on the mountain, the other a statesman on the plain.

The vertical stripes in red, white, and blue (or black) on Sakya Monastery's outer walls are this school's most recognizable emblem.

The three colors are usually explained as symbolizing three bodhisattvas:

• Red — Mañjuśrī, symbolizing wisdom.
• White — Avalokiteśvara, symbolizing compassion.
• Blue (or black) — Vajrapāṇi, symbolizing power.

The three colors side by side amount to painting Sakya's entire path of practice on the wall: wisdom as substance, compassion as form, power as function.

This practice of painting doctrine directly onto architecture is akin to Samye's "building the cosmos into a monastery." It lets anyone approaching Sakya Monastery, even if illiterate, see at a glance what this school intends to say.

Today, most Sakya-system monasteries — whether in Tibet, Nepal, or Europe and America — retain these three stripes. They are no longer mere decoration, but Sakya's identity.

In northern Nepal, in Mustang (also called "Lo"), within the rain-shadow of the Himalayas, lies an exceptionally intact Tibetan-cultural enclave.

Mustang was historically the independent Kingdom of Lo, its inhabitants Tibetan, its language, religion, and customs all in one lineage with Tibet. Because of its remoteness and long closure, its monasteries, murals, and contemplative traditions are preserved so completely that in many respects they surpass those of Tibet proper.

Sakya's influence runs deep here: several Mustang monasteries belong to the Sakya system, preserving fifteenth- and sixteenth-century murals and statues, regarded as a treasure house for the study of Tibetan Buddhist art. Local monasteries such as Tashi Lhakang and Jampa Lhakang still have monks in residence.

Because Mustang only opened limitedly to foreign tourists in 1992, and given its special geology and climate, its cultural relics face the dilemma of preservation versus opening. In recent years both Nepal and China have planned restoration work.

For those seeking Tibetan monasteries, Mustang's significance lies in this: it is a mirror — reflecting another face of Tibetan Buddhism on the southern foothills of the Himalayas, and how far Sakya's influence once reached.

If you have the chance to step into a Sakya monastery, you will roughly pass through this order:

The wall and three stripes — before entering, you first see that red-white-blue wall; it is Sakya's signature.

The main hall (འདུ་ཁང་, du khang) — at the center, Śākyamuni or the Five Sakya Patriarchs; on the sides, deities and protectors. Sakya's statuary is often finely crafted, with the delicacy of the Nepalese style.

The scripture hall and wall of books — the canon standing along the wall is the soul of a Sakya monastery. Monks copy, collate, and recite here.

The protector chapel — enshrining the Pavilion Protector, austere, usually not open to the public.

The debate courtyard — Sakya also has a debate tradition, though not as daily as Gelug.

The visitor's rule is simple: go slowly, stay quiet, do not point at buddha-images with a finger, do not speak loudly or photograph inside the halls; the protector chapel especially should not be entered without invitation.

Sakya's monastery atmosphere differs from Gelug's: Gelug is like a school, Sakya more like a library — quiet, weighty, the air scented with paper and butter-lamp oil.

Almost all of Sakya's sacred sites are concentrated in Upper Tsang (around present-day Shigatse) — Sakya, Ngor, and Nartang monasteries, not far apart. This contrasts interestingly with Nyingma's concentration in Lhoka and Gelug's in Lhasa.

Upper Tsang's geography: the upper Yarlung Tsangpo valley is open, the land fertile, the population relatively dense — the traditional agricultural region of Tibet. Stable agricultural output could support large monasteries and monastic communities — the material basis on which Sakya could operate here for centuries.

Historically, Upper Tsang was long another political center of Tibet. In the fourteenth century, after the Phagdru Kagyu replaced Sakya, the administrative center shifted east to Nedong; in the seventeenth century, Gelug's center of gravity moved to Lhasa. Upper Tsang's political status rose and fell several times, yet its religious weight never diminished — it is Sakya's homeland, and also the seat of the Panchen system.

Q: Where is Sakya Monastery?

A: In Sakya County, Shigatse, Tibet, at about 4,300 meters elevation. It divides into the South Monastery (built 1268) and the North Monastery (built 1073); the South is the main seat, while the North is mostly ruins.

Q: Why does Sakya Monastery look like a fortress?

A: The South Monastery was built during Sakya's rule, combining religious and administrative functions, hence its castle-like layout with square courtyards and high walls and watchtowers—rare among Tibetan monasteries.

Q: Which school does Mustang belong to?

A: Most monasteries in Mustang (Nepal) belong to the Sakya system and preserve many murals and statues from the fifteenth and sixteenth centuries. Nyingma and other lineages also coexist there.

Q: If I can't go to Tibet, how can I draw near these sacred sites?

A: Sakya equally values inner resonance. Reading the Sakya Legshe, learning the 'Three Visions' framework of the Lamdre, and reciting the Mañjuśrī mantra are all ways to connect with this lineage. For Sakya, study itself is a form of pilgrimage.
