The square sits on the footprint of the Roman forum of Barcino, at the intersection of the cardo maximus and the decumanus maximus. Today its opposing buildings are the Palau de la Generalitat, with a medieval core and much sixteenth to twentieth-century reworking, and the Ajuntament, with a medieval Saló de Cent core and a nineteenth-century neoclassical façade. The Jewish quarter, El Call, was attacked in the pogrom of the fifth of August thirteen ninety-one, about three hundred dead, the community effectively destroyed. Per the Wikipedia record of the Jewish quarter and Barcelona Lowdown, abandoned synagogue stones were repurposed into the Royal Palace and the new Generalitat building.

Four surviving Corinthian columns of the temple dedicated to Augustus, on the summit of Mons Taber at the heart of Roman Barcino. The temple was hexastyle, with six front columns and approximately thirty-four in total, roughly thirty-seven metres long and seventeen metres wide. Three columns were rediscovered during late nineteenth-century construction of the Centre Excursionista de Catalunya building; the fourth was moved from Plaça del Rei to complete the group.

Underground, the MUHBA-managed Roman city ruins occupy about four thousand square metres beneath the square, exposed from nineteen thirty-one to nineteen thirty-two when Casa Padellàs was relocated stone-by-stone from Mercaders Street to escape Via Laietana demolition. Above ground, the medieval Palau Reial Major includes the Saló del Tinell, built thirteen fifty-nine to thirteen seventy by master builder Guillem Carbonell on commission of King Pere the Third the Ceremonious, the Capella Reial de Santa Àgata, and the fifteenth-century Mirador del Rei Martí. The museum itself was inaugurated on the fourteenth of April nineteen forty-three under the Francoist regime, founding director Agustí Duran i Sanpere.

Tuesday through Sunday, late morning to early afternoon. The MUHBA underground Roman city site at Plaça del Rei opens at ten in the morning and closes at seven, with last entry at six; an eleven o'clock start at Santa Maria del Pi lets you reach Plaça del Rei inside opening hours if you want to descend into the Roman remains after the audio.
