In both security and architectural news this morning, it’s been reported that the lawns across the roof of Parliament House will soon be closed to the public, as part of a bid to reduce the building’s vulnerability to a possible terrorist attack. The restriction would be against the architectural intention for the lawns, which were designed by Romaldo Giurgola to show that democracy rose out of the ground — and so that people could walk over the top of their elected representatives. The restrictions on access to the lawns would also mean that pranks like the poisoned grass reading “Vote One HEMP” from earlier this year would also be rubbed out.
