Foundation and First Mentions
The city of Castro holds a special place in the history of the State of Paraná, being one of its oldest settlements. Its origins are closely linked to the exploration of Brazil's interior territories in the 18th century. Initially, the area was known as Pouso do Iapó (Rest Stop on the Iapó) — a strategically important halting point on the banks of the Iapó River, where cattle drovers and travellers would stop to rest.
The settlement received official recognition in 1774, when it was elevated to the status of a parish (freguesia). Later, in 1778, Castro became the first officially established "vila" (town) in the Campos Gerais region, which consolidated its administrative significance.
Key Factors of Development
The city's development was driven by a combination of geographical advantages and the economic routes of that era:
- Geography and the Iapó River: Its location on the riverbank made this place a natural point for crossing and resting. The need to overcome the water barrier forced travellers to linger here, which contributed to the growth of the settlement.
- The Tropeiros Route (Caminho das Tropas): Castro was situated on the legendary route connecting the south of Brazil (Viamão) with the markets of Sorocaba. Thousands of mules and cattle were driven along this path, and the city became a vital logistics hub.
- Political Will: The city received its current name in honour of Martinho de Melo e Castro, the Portuguese Minister for Overseas Territories, highlighting the Crown's attention to this region.
Early Cultural and Economic Features
The economy of early Castro depended entirely on servicing caravans. Local residents engaged in growing food for the drovers, repairing equipment, and maintaining inns. This formed a unique Tropeiro culture, traces of which are visible in the gastronomy (dishes made from dried meat and beans), folklore, and even the local dialect.
Furthermore, the fertile lands of the region fostered the development of settled livestock farming and agriculture, allowing the city to maintain economic stability even after the era of horse-drawn caravans came to an end.
