This philatelic sheet brings to life the monumental beauty and dynamism of Baroque art, whose primary aim was to dazzle the senses and make the castle’s interiors appear larger. The issue elegantly links two significant historical sites and showcases the work of leading European masters of their time. The first motif depicts a meticulously executed fresco from Kroměříž Castle, whose magnificent gardens and interiors are now listed as a UNESCO World Heritage Site. The original decoration was created by the Italian painter Carpoforo Tencalla, whose use of colour imbued the Moravian archbishop’s residence with a unique sense of refinement. The second motif takes us to the capital, to the picturesque Troja Palace in Prague. The decoration here, by the painter Abraham Godyn, is a breathtaking example of so-called illusionist painting. Thanks to the masterful use of light and shadow, the dramatic human figures and mythological scenes here literally leap from the walls, blurring the line between reality and art. Why choose this particular issue: Two architectural gems: A combination of a Prague Baroque chateau and a magnificent aristocratic residence listed as a UNESCO World Heritage Site. A masterful illusion of space: A celebration of a historic artistic technique that has transformed cold stone walls into dramatic and vivid scenes.
