Mindon Min intended his stone library to endure five thousand years after the time of the Gautama Buddha. The ambition required industrial-scale craftsmanship. Marble was quarried at Sagyin Hill, 32 miles north of Mandalay, and floated downriver to the capital. In a large shed near Mandalay Palace, teams of monks and lay scholars worked from palm leaf manuscripts kept in the royal libraries, meticulously editing the text of the Tripitaka -- the 'three baskets' of the Vinaya Pitaka, Sutta Pitaka, and Abhidhamma Pitaka. Scribes then copied the verified text onto marble for stonemasons to chisel. Each slab carries 80 to 100 lines of round Burmese script on each side, originally filled with gold ink. A single scribe needed three days per slab; a stonemason could chisel up to 16 lines in a day. All 729 tablets were completed and opened to the public on 4 May 1868.

Each tablet stands 1.07 meters wide, 1.53 meters tall, and 13 centimeters thick, sheltered within its own small cave-like stupa modeled on Sinhalese relic caskets. The 730 structures -- one additional tablet records the project's own history -- are arranged in three concentric enclosures around a central golden pagoda: 42 in the innermost ring, 168 in the middle, and 519 in the outermost. Walking among these rows of white stupas, each topped with a precious gem and a miniature umbrella finial, feels less like visiting a library and more like entering a city built for books. The arrangement is precise, numbered from the west and running clockwise in complete rings, a spatial logic that mirrors the organizational structure of the canon itself.

The gold did not last. When British forces annexed Upper Burma in 1885, troops were billeted in the temples and pagodas around Mandalay Hill. Gems were looted, buildings vandalized, and the gold lettering stripped from all 729 slabs. A petition to Queen Victoria eventually compelled the withdrawal of soldiers from religious sites, and restoration began in 1892 under a remarkable committee: the Abbot of Atumashi Monastery, the royal chancellor Kinwon Min Gyi U Kaung, a Shan prince, and a general from the Burmese army. Following Burmese tradition, relatives of the original donors were given first right to repair what their families had built. The public contributed what it could, but the original gold was replaced with black ink mixed from shellac, lamp soot, and straw ash. The bells vanished from the stupa crowns, and most of the gems were never recovered.

In 1900, a Burmese-born Briton named Philip H. Ripley published the text as a 38-volume print edition, claiming his books were 'true copies of the Pitaka inscribed on stones by King Mindon.' Ripley had been raised in the Mandalay court, schooled alongside the royal princes including Thibaw Min, and had fled to Rangoon at age 17 when palace intrigues turned murderous after Mindon's death. He had his galley proofs checked against the original stones. In 2013, UNESCO inscribed the Kuthodaw tablets on the Memory of the World International Register, formally recognizing what Mandalay's residents had known for over a century: this is the world's largest book. The inscriptions have been re-inked several times since Thibaw's second gilding, and in 1968 public donations cleared the overgrown paths between the caves. Mindon's wager paid off. The teachings carved in stone survived the fall of his dynasty, a colonial occupation, two world wars, and decades of military rule -- still readable, still visited, still standing at the foot of the hill.
