This cover from Ukraine depicts 2 stamps of each type (issued in 2015) featuring the
Drohobych-Tserkva of Saint George in Ukraine and the
Kwiatón-Tserkva of Saint Paraskeva in Poland. The
Wooden Tserkvas of the Carpathian Region in Poland and Ukraine are a group of wooden Orthodox (and some Eastern Catholic) churches located in Poland and Ukraine which were inscribed in 2013 on the UNESCO World Heritage List which explains:
built of horizontal wooden logs between the 16th and 19th centuries by communities of Orthodox and Greek Catholic faiths. The tserkvas bear testimony to a distinct building tradition rooted in Orthodox ecclesiastic design interwoven with elements of local tradition, and symbolic references to their communities’ cosmogony. — World Heritage Centre.
