New stadiums might be stealing the architectural glory at the Rio Olympics, but the national hospitality houses are giving them a run for their money. More than 30 nations have set up camp around Rio de Janeiro in sites that range from a 19th century mansion to a new beachside pavilion and a boat. For many of these ad-hoc HQs – which serve as visitor centers for officials, sportspeople, VIPs and even the public – top designers and architects have been enlisted to provide a taste of their home nation within Brazilian surrounds. Olympians lamenting the conditions of the athletes’ village might want to decamp to these. See highlights in the gallery above.
