This innovative pastel-colored postmodern apartment complex is a popular landmark in the coastal town of Calpe, Spain. It is called Muralla Roja, which means “the red wall”, although it is mostly pink with a bit of baby blue.

Muralla Roja was designed by Spanish architect Ricardo Bofill, and built in the early 1970s. The building was built like a fortress drawing inspiration from the architecture of the North African kasbah. The silhouette of this high-walled, vertical structure is said to mimic the contours of the surrounding cliffs.

The building's striking color palette and strong geometric shapes attract many photographers and “instagrammers”.
