The municipality of Guaíra (33,310 inhabitants in 2020; 56,374 ha) is located 
on the border with Paraguay and Mato Grosso do Sul, here river Paraná, 680 km 
west of Curitiba.
Guaíra was first visited in 1525 by Aleixo Garcia, 
considered as Paraguay's official discoverer, who described the Paraná 
Cataracts. Ciudad Real del Guayrá was established in 1554 on the confluence with 
river Piquiri; established in 1570 on the left bank of the Paraná, Vila Rica do 
Espirito Santo soon outgrew the older royal town as the main center of the old 
province of Guaíra. Controlled by the Jesuits, the two towns were destroyed in 
1631 by Portuguese pioneers and the area was overtaken by Portugal.
Companhia Matte Larangeira, established by Thomas Larangeira after he had been 
granted in 1882 the rights of exploitation of yerba mate, settled in 1902 in 
Guaíra. The new town, then known as Porto Guaíra, was equipped with street 
lighting, freshwater supply, sewage, a chapel, a library, a school, an hospital, 
a phone service etc. Businessman Cézar Prieto Martinez published in 1924 in São 
Paulo a pamphlet pimping Guaíra as "an organization honoring Brazil's industrial 
companies, as a main town owned by a company; a main and the most comprehensive 
since it lacks nothing, a constitution and a police service included".
The 
influence of Matte Larangeira declines in the 1940S, after Getúlio Vargas' 
government had nationalized the company's assets; the shipping company was 
renamed to Serviço de Navegação Bacia do Prata. The March to the West pushed by 
Vargas attracted new inhabitants to the town, which had hitherto been mostly 
inhabited by Paraguayans. In 1947, Governor of Mato Gross Arnaldo Estevão 
Figueiredo terminated Matte Lanjeira's concession, which ended the yerba mate's 
cycle in Guaíra.
Guaíra Falls were the world's biggest series of 
cataracts and a main source of income for the town. As a consequence of the 
Treaty of Itaipu signed by Paraguay and Brazil, the two countries initiated the 
building of the Itaipu Dam; on 13 October 1982, its inauguration caused the 
flooding of Guaíra Falls. This caused the decline of the town, in spite of 
royalties shared with another 13 municipalities as a compensation for the loss 
of tourism income.

The flag and arms 
of Guaíra are prescribed by Municipal Law No. 478 promulgated on 22 May 1973.
Article 6.
The municipal flag of Guaíra, designed by heraldist Arcinoe 
Antônio Peixoto, shall be horizontally divided into three stripes, the lateral, 
blue, of 5 units in width, and the central, yellow, of 4 units, superimposed 
with a red stripe of 1 unit starting from the angle of a yellow isosceles 
triangle placed along the hoist and charged with the municipal coat of arms.
§1. In compliance with the tradition of Portuguese heraldry, of which we 
inherited the canons and rules, municipal flags have to be divided into eight, 
six, four or three parts, using the same colors as those of the field of the 
coat of arms and being charged in the center or at hoist with a geometric figure 
inscribing the municipal coat of arms.
§2. The municipal flag of Guaíra obeys 
this general rule, being divided into three horizontal stripes. The coat of arms 
featured on the flag represents the municipal government, while the yellow 
isosceles triangle containing it represents the town proper as the seat of the 
municipality. The triangle is the heraldic symbol of liberty, equality and 
fraternity; yellow is a symbol of glory, splendor, greatness, wealth and 
sovereignty. The central yellow stripe superimposed with a red stripe represents 
the spread of municipal power to all parts of the territory. Red is a symbol of 
dedication, patriotic love, audacity, intrepidity, courage and valiance. The 
blue lateral stripes represent the rural properties existing on the municipal 
territory. Blue is a symbol of justice, nobleness, perseverance, zeal, loyalty, 
beauty and recreation.
Article 7.
In compliance with heraldic rules, 
the municipal flag shall have the official dimensions prescribed for the 
national flag, 14 units in width on 20 units in length.
Article 19.
The coat of arms of Guaíra, designed by heraldist Arcinoe Antônio Peixoto, shall 
be described in proper heraldic words as follows.
A Samnite shield surmounted 
by an eight-towered mural crown argent. On a field azure an anchor or fouled 
gules surrounded by two fishes or in pale in base four rocks sable linked by 
three hanging bridges argent over three waterfalls argent wavy azure. The shield 
supported dexter and sinister by branches of coffee fructed proper crossed in 
base and superimposed with a scroll gules inscribed in letters argent with the 
toponym "GUAÍRA".
The coat of arms has the following symbolic 
interpretation.
a) The Samnite shield used to represent the arms of Guaíra 
was the first style of shield introduced to Portugal by French influence, 
inherited by Brazilian heraldry as the evocation of the colonizing race and main 
builder of the nation.
b) The mural crown surmounting it is the universal 
symbol of domains' coats of arms; argent (silver) with eight towers, only four 
of them visible in perspective view, it classifies a 2nd rank town, that is, the 
seat of a county.
c) Azure (blue) is a symbol of justice, nobleness, 
perseverance, zeal and loyalty.
d) The anchor or (yellow) fouled gules (red) 
represents the port of Guaíra, one of the most important in the Bay of Paraná, 
which drains product of West Paraná to Mato Grosso and São Paulo.
e) The 
fishes or (yellow) highlight the significance of fishing for the municipal life 
and also as a tourism activity.
f) Or (yellow) is the heraldic symbol of 
glory, splendor, greatness, wealth and sovereignty.
g) The shield's base 
features the monumental Seven Cascades Waterfall, an international tourism spot.
h) Sable (black) symbolizes prudence, moderation, austerity, modesty, firmness.
i) Argent (silver) is a symbol of peace, friendship, work, purity and religious 
feeling.
j) The coffee branches represent the main crop offered by the 
generous and fertile soil, a source of income for the municipality and the state 
of Paraná.
k) Gules (red) is a symbol of dedication, patriotic love, 
audacity, intrepidity, courage and valiance.
