The Calyx

This guide to The Calyx in Sydney at the Royal Botanic Garden traces the removal of the glass pyramid that stood on this spot from the early 1970s until 2015, and the building that rose in its place, named for the ring of sepals that protects a flower bud before it opens. It follows why the pavilion opened in June 2016, timed to the garden's two-hundredth anniversary, and how its columns are designed to reveal the plants inside gradually rather than all at once. Look up as you walk beneath the white colonnade to see the effect for yourself.
