3House of the Temple, Washington, D.C., USA

Designed by architect John Russell Pope, the House of the Temple is the headquarters of the Scottish Rite of Freemasonry in Washington, D.C. This imposing neoclassical building is filled with esoteric symbolism, sacred geometry, and references to ancient knowledge. With large portions of the interior off-limits to the public, the structure fuels speculation about secret rituals and hidden archives. For many, it represents the very essence of Freemason mystery.
