2The House of the Temple, USA

Located in Washington, D.C., the House of the Temple serves as the headquarters of the Scottish Rite of Freemasonry. Designed by famed architect John Russell Pope, the building is a perfect example of symbolic architecture.

From the number of steps to the layout of the rooms, everything has layered meaning. With restricted access and strong ties to Freemasonry’s rituals, the building invites speculation about what secrets might lie within its marble halls.
