La Muralla Roja (lit. 'the Red Wall') is a postmodern apartment complex in Manzanera, Calpe, Spain. It is designed by Spanish architect Ricardo Bofill for the client Palomar S.A. in 1968 and fully constructed by 1973. It has been ranked among "Ricardo Bofill's 10 Most Iconic Works".

In designing the building, Bofill referenced the architecture of North African casbahs and Arab Mediterranean architectural styles. It reinterprets the casbahs in an avant-garde fashion while incorporating the traditional elements like plazas (courtyards), staircases and bridges that connect all the apartments to one another.

As a residency, it holds several amenities such as two commercial stores, a sauna and a restaurant all on the first level. On roof terraces there are solariums and a swimming pool exclusively for use of its residents.

La Muralla Roja is referred to as a housing estate that has fifty apartments/ living spaces. There are three different styles and sizes of apartments: Studio apartments of approximately 60 square meters, two bedroom apartments of 80 square meters, and three bedroom apartments of approximately 120 square meters.
