Passeig Olímpic, 5-7

"The sprawling site of the 1992 Olympic Games is worth the trip to Montjuïc. You will see the Palau Sant Jordi, an indoor sports complex, the Picornell swimming pools, and most famously, the Olympic Stadium Lluís Companys, built in 1929 in a bid to host the 1936 games (the outbreak of the Spanish Civil War scuttled that chance). Tour the refurbished 55,000-seat stadium, which now hosts big musical acts and soccer competitions, and visit the Olympic and Sports Museum next door. A vast esplanade lined with curious columns that resemble smokestacks is one of the area’s most distinguishing features, as is Santiago Calatrava’s soaring all-white communications tower with its needle-shaped spire."
