P.R. CHINA

This cover with a total of 10 stamps affixed on it came from P.R. China. It includes a complete set of 4 stamps issued in 2004 celebrating the Danxia Mountains. China Danxia, or Danxia landform of China, is a subset of the Danxia landforms which, in August 2010, entered the World Heritage List. It refers to various landscapes found in southeast, southwest and northwest China that "consist of a red bed characterized by steep cliffs". It is a unique type of petrographic geomorphology found in China. Danxia landform is formed from red-coloured sandstones and conglomerates of largely Cretaceous age. The landforms look very much like karst topography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called "pseudo-karst" landforms.

GERMANY

These 2 covers with special postmarks came from Germany and both of them 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.

This cover came from Norway and was posted at the Arctic Post Office of Pyramiden. Pyramiden (literally 'The Pyramid') is an abandoned Soviet coal mining settlement on the Norwegian archipelago of Svalbard which has become a tourist destination. Founded by Sweden in 1910 and sold to the Soviet Union in 1927, Pyramiden was closed in 1998 and has since remained largely abandoned with most of its infrastructure and buildings still in place, the cold climate preserving much of what has been left behind. Since 2007, there have been efforts to make it a tourist attraction; the town's hotel was renovated and reopened in 2013. The Pyramiden hotel also houses the Pyramiden Museum as well as a post office and a souvenir shop, where surely this cover was cancelled. There was a small hotel built of old shipping containers near the harbour, but this has closed since the hotel is now renovated and open for guests. There are no plans to renovate and reopen the whole settlement.
