The Roman Catholic Church of St. Nicholas is the second oldest Roman Catholic church standing in Kyiv.
It was constructed in 1899–1909 and was built by the Latin Rite Catholic community in a Gothic type construction, by architects Władysław Horodecki and Emilio Sala.
The building itself is beautiful, in winter, when there is snow it resembles Hogwarts in some way. It may be a nice isea to put it on the stamp.
It's also one of the most noteable landmarks in Kyiv.
