Corpus Christi is Toledo’s most important festival and one of its oldest. Although its exact date of origin is unknown, it is recorded as having been celebrated in the 15th century. This solemn religious procession is celebrated on the day of the Corpus Christi and presided by the Archbishop of Toledo, cardinal primate of Spain. The city’s historic streets, especially decorated for the occasion, provide the backdrop for this striking procession. The highlights are the Monstrance, a priceless work of craftsmanship in gold and silver dating from 1515 and weighing about 160 kilos; and the distinctive and traditional retinue of followers made up of the different religious fraternities and guilds.
