L'illa Diagonal, "the diagonal block" in Catalan, was the first of a half dozen ambitious mall/office complexes built in the 1990s. Because of its size, it soon became known as "Super Block." Architects Rafael Moneo and Manuel de Solà-Morales designed it to suggest New York City's Rockefeller Center laid horizontally. It has continued to expand, now having over 170 shops, a sports center, two high-end hotels, a dance hall, two schools, restaurants and conference center. Primark, the Scottish retailer, is the anchor department store, and there's a grocery store in the basement.
