KOSOVO

This cover came from Kosovo and features a miniature sheet issued in 2017 celebrating the "Patriarchate of Pec Monastery", some of the monuments included at the UNESCO world heritage site known as "The Medieval Monuments in Kosovo". The Medieval Monuments in Kosovo are a World Heritage Site consisting of four Serbian Orthodox Christian churches and monasteries which represent the fusion of the eastern Orthodox Byzantine and the western Romanesque ecclesiastical architecture to form the Palaiologian Renaissance style. The construction was founded by members of Nemanjić dynasty, the most important dynasty of Serbia in the Middle Ages. The sites are located in the modern-day Kosovo. In 2004, UNESCO recognized the Dečani Monastery for its outstanding universal value. Two years later, the site of patrimony was extended as aerial nomination, to include three other religious monuments: Patriarchate of Peć Monastery, Our Lady of Ljeviš and Gračanica Monastery. In 2006 the property was inscribed on the list of World Heritage in Danger due to difficulties in its management and conservation stemming from the region's political instability. There is also an ongoing controversy over Kosovo's bid to join the UNESCO, which would result in the sites being listed as part of Kosovo and not Serbia. These monuments have come under attack, especially during the ethnic violence in 2004, during Kosovo's UNMIK rule, when the Our Lady of Ljeviš was heavily damaged. In October 2015 Kosovo was recommended for membership by the UNESCO Executive Board bus UNESCO has not accepted Kosovo as a member.

GERMANY

A cover from Germany with a special postmark celebrating the 1200th. anniversary of the Princely Abbey of Corvey. The Princely Abbey of Corvey (German: Fürststift Corvey or Fürstabtei Corvey) is a former Benedictine abbey and ecclesiastical principality now in North Rhine-Westphalia, Germany. It was one of the half-dozen self-ruling princely abbeys of the Holy Roman Empire from the late Middle Ages until 1792 when Corvey was elevated to a prince-bishopric. Corvey, whose territory extended over a vast area, was in turn secularized in 1803 in the course of the German mediatisation and absorbed into the newly created Principality of Nassau-Orange-Fulda. Originally built in 822 and 885 and remodeled in the Baroque period, the abbey is an exceptional example of Carolingian architecture, the oldest surviving example of a westwork, and the oldest standing medieval structure in Westphalia. The original architecture of the abbey, with its vaulted hall and galleries encircling the main room, heavily influenced later western Romanesque and Gothic architecture. The inside of the westwork contains the only known wall paintings of ancient mythology with Christian interpretation in Carolingian times. The former abbey church was listed as a UNESCO World Heritage Site in 2014.

BRAZIL

This cover from Brazil depicts 2 stamps. The small stamp of 0,23 R$ shows a picture of the Pantanal. The Pantanal Conservation Area is a natural region encompassing the world's largest tropical wetland area, and the world's largest flooded grasslands. It is located mostly within the Brazilian state of Mato Grosso do Sul, but it extends into Mato Grosso and portions of Bolivia and Paraguay. It sprawls over an area estimated at between 140,000 and 195,000 square kilometres. Various subregional ecosystems exist, each with distinct hydrological, geological and ecological characteristics; up to 12 of them have been defined. Roughly 80% of the Pantanal floodplains are submerged during the rainy seasons, nurturing a biologically diverse collection of aquatic plants and helping to support a dense array of animal species. Pantanal Conservation Area was declared a UNESCO World Heritage Site in 2000.
