Corpus Christi Holiday is always held on Thursday after octave of Pentecost. It is a holiday of the Holiest Sacrament and also the opportunity to publicly testify faith. On this day every parish organizes a Corpus Christi procession in the morning. In such processions we find first girls who sprinkle flower petals before the Holiest Sacrament, then servers and priests and nuns, colour parties and then baldachin with priest and the Holiest Sacrament and after it there are church goers. The procession leads the believers to 4 altars which are especially prepared for this celebration on the way of the march. Usually, such processions take about 1-2 h. Processions vary from region to region. In some areas they are very celebrative and the procession goers wear traditional costumes. Visiting Poland on this day you have to be prepared for numerous traffic stops which are caused by processions. In most cases, police officers guide and stop the vehicles. Still, the holiday celebrations tend to be original and interesting for tourists.
