This cover from United Nations (Office of New York) depicts 4 stamps (2 of each type) with pictures of two world famous bridges, both inscribed as World Heritage Sites by UNESCO: the
Forth Bridge in Scotland, United Kingdom, and the
Old Mostar Bridge, in Bosnia and Herzegovina. The
Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, 14 kilometres west of central Edinburgh. Completed in 1890, it is considered as a symbol of Scotland (having been voted Scotland's greatest man-made wonder in 2016), and is a UNESCO World Heritage Site since 2015. The UNESCO site in Bosnia and Herzegovina encompasses the Old Bridge and the surrounding area. The Ottoman bridge, which crosses the Neretva river, was commissioned by Suleiman the Magnificent and completed in 1566/67. In 1993, during the Bosnian War, it was deliberately shelled and destroyed by the Croatian Defence Council. After the war, the bridge was rebuilt using traditional construction methods and local materials, and reopened in 2004. In 2005, all the historic area around the bridge was declared a World Heritage Site by UNESCO.
