Abstract
Gothic architecture is one of the oldest surviving architecture in Slovakia. The Church of Pauline Order in Trebišov has many building phases; its entrance stone portal belongs to the later phase dated about the second half of the 15th century. Paper focuses on an architectural features and geometry of this portal. Portal has clearly a geometrical construction that is compared to another late gothic portal from church in Handlová. Conclusion suggests, that ratio of the entire portal dimensions is close to 4 : 3, proportions of jamb and opening widths are 1 : 4 : 1 part of the overall portal width and there highly probably existed some simple method of determining position of pointed arch arches.
