While Poland has lifted many of its COVID-19 curbs, public health officials have urged people to don face masks during ceremonies and remain two metres away from others to maintain safety.
In many dioceses, ceremonies have been scaled down from previous years, state news agency PAP reported.
The feast of Corpus Christi is one of the oldest in the Catholic Church and has been marked since the 13th century.
During Poland’s often-turbulent history, especially when the nation was under foreign rule for 123 years until 1918, Corpus Christi processions were strongly patriotic as well as religious in flavour.
The day is a public holiday in the country.
Poland at the end of last month relaxed face mask rules, and it also allowed public gatherings of up to 150 people as it moved to the next phase of easing its coronavirus lockdown.
The government lifted all restrictions on how many people can gather in places of worship though social distancing guidelines still apply.
On the last Sunday of May, Catholic shrines around the country threw their doors wide open to worshippers after weeks of restrictions amid the COVID-19 outbreak.
A total of 27,842 people have tested positive for the COVID-19 disease in Poland, with 1,206 deaths from the coronavirus so far, officials said on Wednesday evening.
About 93 percent of Poles declare themselves to be Catholics, according to a statistics institute.
