Antonvilla
Antonvilla is a small imperial residence of the House of Götzö-Thomaz-Rocha dynasty in Floriano, Piauí, Brazil, later residence of the Pannonian Monarchy. After the death of Archduke Anton in November 2021, Archduke Ari inherited a property that served as residence of the late archduke for the last thirty years of his life. With a huge extension, the former archducal residence was intended for the exploitation of real estate, while part of the park was intended for the construction of a new residence, Antonvilla. The construction was planned to start in late 2021, but the plan was dropped and the main residence became the seat of the King of Pannonia due the foundation of Pannonia.
However, for a short period of time, it became the seat of the Ameroslavian Monarchy, with the King occupying the house as his official residence when in the kingdom, the courtyard considered the city of Lennartgrade, capital of Ameroslavia. Antonvilla was also the center of the administration of the Provisional Government of the State of Slavs of America before the city being renamed Arigrade, in tribute of King Ari of Pannonia.
