Great Monuments Build Time: One Day Against the Centuries

Great sacred monuments have almost always been built across generations. The Great Pyramid took about 26 years; the Taj Mahal complex, about 21; Angkor Wat, about 28; Borobudur, about half a century. The Sagrada Família in Barcelona, begun in 1882, saw its central tower completed in 2026 — the centenary of its architect’s death — and is still not finished.

Bhutan’s own precedent is closer in kind. The 108 chortens on the Dochula pass were raised in about six months, in the first half of 2004.

Project 108 proposes to raise 108 Jangchub Chortens, each about fifteen metres tall, in a single day — 1 November 2026 — with close to 40,000 volunteers. On a linear scale the bar would be invisible beside the others, which is why the chart uses a logarithmic one: each gridline is ten times the one before.

The comparison is of time, not of size — a fifteen-metre chorten is not a pyramid — and of different things: the others’ full construction periods, against Project 108’s planned day of collective raising, which follows months of preparation. What it shows is how rare it is for a monument to be raised by everyone at once.

The full comparison is in Project 108 by the Numbers; why the chortens are raised in a single day is told in Project 108 in One Day, and why monuments now take so long everywhere else in Great Monuments Today.
