Derge sits in a high valley in Kham, the eastern region of traditional Tibet that now falls within China's Sichuan Province, roughly 400 kilometers west of Chengdu. The Parkhang, which means "printing house" in Tibetan, is associated with Gonchen Monastery, the great Sakya monastery that anchors the town. What makes the Parkhang extraordinary is not its age alone but its continuity. The woodblocks from which books are printed were hand-carved by artisans over the course of centuries. Each block is a plank of wood with text carved in mirror image, and the collection represents the most comprehensive archive of Tibetan literature in existence. The subjects range far beyond religious texts to encompass history, medicine, biography, technology, and literature.

Denba Tsering, the fortieth King of Derge, founded the Parkhang in 1729 with spiritual guidance from the 8th Tai Situ Panchen Chokyi Jungne. The king ruled from 1678 to 1739, and his decision to establish a printing temple reflected the Derge Kingdom's long tradition as a patron of Tibetan culture and learning. China has recognized the Parkhang as a National Protected Heritage Site, an acknowledgment of its cultural weight that coexists uneasily with the political pressures faced by Tibetan institutions elsewhere in the region. The Parkhang prints Buddhist sutras and commentaries, thangka painting guides, and works across the full range of Tibetan intellectual life. It is, in effect, both a library and a publisher, preserving knowledge by the physical act of reproducing it.

Thirty printing stations remain in working condition. At each one, two printers work in tandem: one inks the carved wooden block and cleans it in a trough after each impression, while the other rolls paper across the surface using a hand roller. The ink is colored with cinnabar, giving the printed text its distinctive red hue. The result is a page that looks much the same as one printed here in the 18th century. There is something deliberately unhurried about the process. In an age when digital reproduction can duplicate a text in milliseconds, the Parkhang's method requires human hands at every stage: carving the block, mixing the ink, aligning the paper, applying the pressure. Each printed page carries the physical evidence of the person who made it. More than a hundred workers are employed in the printing house, maintaining a tradition that predates the industrial revolution in Europe.

The Parkhang building itself is considered sacred. Pilgrims visit not only to see the printing but to circumambulate the structure, walking clockwise around it as an act of devotion. This blurs the boundary between workshop and temple in a way that is characteristic of Tibetan culture, where the preservation and transmission of knowledge is itself a spiritual practice. The woodblocks are not merely tools; they are objects of reverence, each one representing countless hours of skilled labor in service of the dharma. Visitors who make the difficult journey to Derge find a place where the past is not preserved behind glass but actively, physically, continuously reproduced. The sound of paper meeting wood, the smell of cinnabar ink, the coordinated motion of the printing teams - these are not reenactments for tourists. They are the daily work of an institution that has outlasted empires.
