Author of drawings engravings is a renowned Slovak engraver František Horniak who created several stamps with architectonic motives in cooperation with Karol Felix. Wooden churches are unique architectonic monuments based on the tradition of wooden, vernacular Carpathian architecture. In Eastern Slovakia there are about 50 mostly Greek Catholic churches in the surroundings of Bardejov and Snina. 27 of them were proclaimed National cultural monuments. The oldest preserved churches in Hervatov and Tročany were built in the Middle Ages at the turn of 15th and 16th century. Other churches are from the New Age, from 17th and 18th century. Local folk carpenters built churches from wooden log-house constructions without a single iron nail because nails reminded them of crucifixion of Jesus Christ. Churches consist of the antechapel, nave and sanctuary with altar, evoking Holy Trinity. All three spaces were finished by towers gradually higher towards the West. Roofs of churches consisted of hand-made wooden shingles. In the past, iconostas and rich wall paintings were found in the interior of churches. Iconostas is light wooden construction separating space for believers from the space for preachers and was decorated by icons. Ceilings of churches were also decorated with paintings. In July 2008 in Quebec, Canada, eight wooden churches in Slovakia were added to the UNESCO World Cultural and Natural Heritage List. Amongst these are the churches in Hervatov, Bodružal and Ladomírová. Ľubica Pavlovičová, Jana Švecová, Martin Vančo
