"Obrona" celebrations, dedicated to the Polish defence of Lviv, became a major Polish public celebration, and were integrated by the Roman Catholic Church into the traditional all Saints Day celebrations in early November.Military parades and commemorations of battles at particular streets within the city, all celebrating the Polish forces who fought against the Ukrainians in 1918, became frequent, and in the 1930s a vast memorial monument and burial ground of Polish soldiers from that conflict was built in the city's Lychakiv Cemetery.
