The Las Arenas bullring formally re-opened to the public on 25 March 2011 as a major new mixed-use leisure, entertainment, and office complex. The historic bullring, built at the end of the 19th century, fell largely into disuse during the 1970s due to the declining popularity of bull fighting in Catalonia. However, the strong civic and cultural role which the building played in the life of Barcelona over nearly a century led to a decision by the city council not to demolish the facade. The design has created an open and accessible entrance to the new building at street level. In addition, an adjacent building - the 'Eforum' - provides retail and restaurants at ground and first-floor levels, with four levels of offices above.
The approach has involved the most advanced architectural and engineering technologies to re-establish the original building as a visually striking landmark for the city. The most spectacular aspect of the intervention is the inclusion of a 100-metre-diameter habitable 'dish' with a 76-metre- diameter domed roof, floating over the facade of the bullring and structurally independent from it to cover the various activities taking place below. This 'plaza in the sky' incorporates large terraces around the perimeter with space for cafes and restaurants with stunning views over the city. New plazas are also created at street level to provide connections with the existing metro station and neighboring Parc Joan Miro. The development links strongly to the nearby Fira de Barcelona - a key European business exhibition venue attracting 3.5 million visitors annually- and the neighboring districts of Eixample and Sants-Montjuic.
Richar Rogers' practice sets out to re-establish Las Arenas as a 21st-century landmark for the city. This involved retaining the entire existing facade as well as reintegrating what had become an isolated traffic island into the city fabric. The design includes a new leisure and retail development within this facade and has also created significant areas of public realm both in the new dome structure - with its 360-degree roof terrace rising above the existing wall - and at the surrounding street level, which will help to revitalize this part of Barcelona.
