It's huge, it's delicate and it's historically and artistically significant, so cleaning and conserving the Great Hall Tapestry is no mean feat.
Part of the process of cleaning one of the most awe-inspiring artworks at Parliament House includes deep-freezing the material to kill any insects or eggs that may have infested it. Just another version on Capital Hill of putting your enemies in the deep-freeze.
The tapestry, measuring 20-metres wide and nine-metres high, has hung in the Great Hall of Parliament House since the building was opened in 1988.
