Paraguay ( ; ] ; Guarani: "Paraguái" , ] ), officially the Republic of Paraguay (Spanish: "República del Paraguay" ; Guarani: "Tetã Paraguái" ), is a landlocked country in central South America, bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest.  Paraguay lies on both banks of the Paraguay River, which runs through the center of the country from north to south.  Due to its central location in South America, it is sometimes referred to as "Corazón de Sudamérica" ("Heart of South America").  Paraguay is one of the two landlocked countries (the other is Bolivia) outside Afro-Eurasia, and is the smallest landlocked country in the Americas. The County of Coimbra (Portuguese: "Condado de Coimbra" ) was a political entity consisting of the lands of Coimbra, Viseu, Lamego and Santa Maria da Feira, in modern Portugal.  It arose within the Kingdom of Asturias following the reconquest of the region, when the lands were granted to count Hermenegildo Gutiérrez, who over the next four decades was largely responsible for the resettlement of the depopulated province.  He and his immediate successors were counts, and held Coimbra, but were not explicitly Counts of Coimbra, although they are sometimes referred to as such retrospectively.  The first nobleman specifically to be called Count of Coimbra was Gonzalo Muñoz, who was probably a scion of the family of Hermenegildo.  Becoming Count around 959, he was one of the most powerful noblemen in the western part of the kingdom until he rose in rebellion against king Bermudo II of León and was probably killed during the region's subjugation.  The degree to which his successors were alienated from their monarch can be seen when, following the region's recapture in 987 by the Moors of Al-Mansur, Gonzalo's sons joined that general in his sack of Santiago de Compostela in 997.

The theatre was designed and constructed by the architect François Debret on the site of the former Hôtel de Choiseul.
