La Muralla Roja, designed by Ricardo Bofill in 1968 and completed in 1973, is an iconic apartment complex in Spain that feels like it could be a set for SquidGame. Its vibrant walls and dramatic cliffside setting give it a distinctively cinematic quality. Inspired by the Kasbah and adobe-inspired architecture of North Africa, this constructivist building includes 50 residences, ranging from 60 m² studios to two- and three-bedroom apartments of 80 and 120 m².

These homes are interconnected by a labyrinth-like network of patios and corridors, reinforcing its fortress-like design. The bold red exterior contrasts with the natural surroundings, while the interior’s blue, indigo, and violet hues complement the sky, making it both architecturally significant and visually striking.
