A monochrome tribute to Hong Kong’s Bonham Road Government Primary School. Its spiral staircase embodies timeless geometry, yet the true heart of the space lies in a rare Foucault Pendulum suspended within. Installed to demonstrate Earth’s rotation, the pendulum became more than a scientific device: a preserved artifact and silent witness to generations of students. Merging architectural elegance with scientific heritage, the image celebrates education as a space where form, knowledge, and memory intertwine.
