The Duchy of Marienbourg is a sovereign state formed by a series of enclaves and exclaves in the Brazilian Highlands, southeastern South America, in a subregion called Southern Cone, just above the Tropic of Capricorn. With a total area of approximately 0.49 km² (0.19 sq mi), Marienbourg is entirely surrounded by Brazil, which does not recognize its sovereignty and independence. Landlocked, the country has no coast or lakes, but is bathed by the Astyanax River, a national tributary of the Pardo River which rises in Brazil. The country has a temperate and oceanic climates, featuring cool summers and mild winters.

Physiographically, Marienbourg is uniform, located on steep terrain, about 900 meters above sea level, in the Atlantic plateau region. Geopolitically, the country is divided between urban and rural areas. Its flora is entirely composed of the Atlantic rainforest, it is divided into rupestrian grasslands and montane forests. The topography is highly suggestive of a volcanic crater due given that the region's rocks are indeed igneous and there are hot springs; in reality, the country is within an ancient caldera.


Marienbourg covers a territory of 0.49 km² (0.19 sq mi) divided into five enclaves within the Brazilian municipality of Poços de Caldas, in the eastern highlands of South America. Due to the proximity between the enclaves and the small size of the country, Marienbourg's physical geography is rather simple.

Rural area

The Rural Area is the official designation given by the Marienbourgish Government to the region in which the municipality of Pomerade is located. It consists of a relatively flat valley at the top of a hill, between mountains of the Mantiqueira mountain range. The Rural Area exists surrounded by the Brazilian Plateau. Its biogeography is dominated by seasonal forests. Due to its high altitude, the climate is temperate and mild, with the lowest average temperature in the country. Due to its location and the acidic richness of the soil, most of the rural area is used for agriculture. The region, however, conserves the Duke's National Park (which houses the Zederthal Forest), and is crossed by the Astyanax River, a national tributary of the Pardo River of origin Brazilian. There is also located the Grünorange Peak, the highest point in the country, at 1,210 meters high. Due to its forests and simple terrain, the Rural aare are home to a vast fauna that sometimes includes even large mammals such as jaguars and manned wolves.

Urban area

The Urban Area is the official designation given by the Marienbourgish Government to the region in which the capital municipality of Blauberga is located. The territory is, as the name implies, extremely urbanized, and consists of four private properties, one of which is commercial, and their surroundings. The very sparse vegetation in the Urban area consists mainly of imported araucaria pines and small shrubs native to the local seasonal forests. The absence of vegetation, as well as the lower altitude in relation to the rural area, are enough to create conditions in the Urban area for a oceanic climate, with recurrent monsson.


Marienbourg experiences a temperate climate in its oceanic variety, due to its high altitude and relative proximity to the ocean (243 km), which allows the on-shore flow of humidity and Antarctic winds to reach the national territory. As a result, the country basically has two well-defined seasons: winter, from April to September, characterized by being dry and cool, reaching freezing temperatures in its most severe months, although rarely below 1°C, and summer, from October to March, which is quite humid. and rainy, with mild temperatures that very rarely approach 40°C.

The absolute minimum and maximum temperatures recorded were -7.2 °C and 35 °C, respectively. Annually it rains for approximately 105 days, although this number is a total of time added and the rain is distributed throughout the year, but much more frequent in summer. Due to its altitude and the mineral composition of its soil, in addition to the confluence of winds of opposite temperatures in the region, rain in Marienbourg is often accompanied by lightning and thunder, and thunderstorms are common, as are hail. Frost are common in the colder months.


Marienbourg is located in the division zone between the Atlantic forest and the South American tropical savannah called cerrado. This confluence zone is strongly characterized by the intercalation of the two different biomes, giving rise to subtropical forests (cerradão), locally known as catanduva, marked by orchard-like vegetation with trees about 6 meters high and which rarely experience the droughts characteristic of cerrado grasslands (cerrado strictu senso).

Typically, the Atlantic and interior fauna of the cerrado mix, with around 500 mammals native to both biomes interspersing their territories, in addition to more than a thousand species of birds. Some species, such as the jaguar, the maned wolf, red brocket deer and several species of capuchin monkeys and toucans, in addition to ungulates such as tapirs commonly inhabit both biomes and especially the zone transition between them.
