PORTUGAL

This cover from Portugal depicts 2 stamps of the same type (from a set of 4) celebrating Lisbon as the Ibero-American Capital of Culture in 2017. The stamp features a picture of Machu Picchu, Peru, inscribed as a Cultural Heritage site since 1983, Machu Picchustands 2,430 m above sea-level, in the middle of a tropical mountain forest, in an extraordinarily beautiful setting. It was probably the most amazing urban creation of the Inca Empire at its height; its giant walls, terraces and ramps seem as if they have been cut naturally in the continuous rock escarpments. The natural setting, on the eastern slopes of the Andes, encompasses the upper Amazon basin with its rich diversity of flora and fauna.

Rio de Janeiro: Carioca Landscapes between the mountain and the sea:

The site, inscribed as Cultural Heritage by Unesco since 2012,  consists of an exceptional urban setting encompassing the key natural elements that have shaped and inspired the development of the city: from the highest points of the Tijuca National Park’s mountains down to the sea. They also include the Botanical Gardens, established in 1808, Corcovado Mountain with its celebrated statue of Christ, and the hills around Guanabara Bay, including the extensive designed landscapes along Copacabana Bay which have contributed to the outdoor living culture of this spectacular city. Rio de Janeiro is also recognized for the artistic inspiration it has provided to musicians, landscapers and urbanists.

Historic Sanctuary of Machu Picchu:

Machu Picchu, inscribed as Cultural Heritage site since 1983, stands 2,430 m above sea-level, in the middle of a tropical mountain forest, in an extraordinarily beautiful setting. It was probably the most amazing urban creation of the Inca Empire at its height; its giant walls, terraces and ramps seem as if they have been cut naturally in the continuous rock escarpments.
