Bhutan competed at the Rio Summer Games from 5 to 21 August 2016.  No Bhutanese athlete has ever won a medal at the Olympics.  The two athletes who were selected to represent Bhutan at the Rio Games were Karma in the women's individual archery tournament and Kunzang Lenchu in the women's 10 metre air rifle shooting contest.  Along with the two athletes, the Secretary General of Bhutan's Olympic Committee, and two coaches, the country's delegation was led by the heir presumptive to the Bhutan throne Jigyel Ugyen Wangchuck.  Karma was selected as the flag bearer for the opening ceremony while Lenchu held it at the closing ceremony.

The Dragons were successful on the field, making it to 4 World Bowls (1991, 1997, 1999, 2001) and winning World Bowl V in 1997.  The team was made part of the FC Barcelona organization in 2002 as the FC Barcelona Dragons.  Despite these efforts, the franchise's fan support decreased and the team began to struggle financially.  After the 2003 season, the Dragons were discontinued and they were replaced in the league by the Cologne Centurions.

Estadi Olímpic Lluís Companys (] , formerly known as the Estadi Olímpic de Montjuïc and Estadio de Montjuic) is a stadium in Barcelona, Catalonia, Spain.  Originally built in 1927 for the 1929 International Exposition in the city (and Barcelona's bid for the 1936 Summer Olympics, which were awarded to Berlin), it was renovated in 1989 to be the main stadium for the 1992 Summer Olympics. For the Summer Olympics, there are 53 venues that have or will be used for equestrian.  From 1912 to 1992, the events took place in more than one venue.  Since the 1992 Summer Olympics, the equestrian events have taken place on a single venue in an effort to reduce costs.  During the 1964 to the 1980 Summer Olympics, an equestrian event was the final event before the closing ceremonies of the respective Olympics.  The last equestrian event that took place at the main stadium was at the 1988 Summer Olympics though it was not the final event before the closing ceremonies.  That honor would fall for the end of the men's marathon event.  Stockholm Olympic Stadium is the only equestrian venue to serve host for more than one Summer Olympics, doing so in 1912 and 1956.
