Later known as Leningrad (in the former USSR), the city is closely associated with the October Revolution. Its architectural heritage reconciles the very different Baroque and pure neoclassical styles, as can be seen in the Admiralty, the Winter Palace, the Marble Palace and the Hermitage.

Namibia, a new country in my collection! This cover depicts a miniature sheet celebrating the World Heritage Site Twyfelfontein or /Ui-/ / aes. Twyfelfontein (Afrikaans: uncertain spring), officially known as ǀUi-ǁAis (Damara/Nama: jumping waterhole), is a site of ancient rock engravings in the Kunene Region of north-western Namibia. It consists of a spring in a valley flanked by the slopes of a sandstone table mountain that receives very little rainfall and has a wide range of diurnal temperatures. The site has been inhabited for 6,000 years, first by hunter-gatherers and later by Khoikhoi herders. Both ethnic groups used it as a place of worship and a site to conduct shamanist rituals. In the process of these rituals at least 2,500 items of rock carvings have been created, as well as a few rock paintings. Displaying one of the largest concentrations of rock petroglyphs in Africa, UNESCO approved Twyfelfontein as Namibia's first World Heritage Site in 2007.

his cover came from South Africa and depicts a complete set issued in 2011 celebrating the World Heritage Site Cape Floral Region Protected Areas. The site is inscribed at UNESCO's since 2004 and comprises a series of national parks and protected areas that are home to the plants of one of the six floral kingdoms of the world. The area is remarkably rich in biodiversity: although it covers less than 0.5% of Africa, it is home to 20% of plan species of the continent. The fynbos vegetation of fine-leaved shrubland is adapted to a Mediterranean climate of the region and to occasional fires. Many plants rely on pollination and seed dispersal by insects, birds, and mammals. Several plant species are of conservation concern.
