Aveiro’s history dates back to the Roman era, when it was an important center for salt production and trade. The city’s name is derived from the Latin *Aviarium*, meaning "bird’s nest," reflecting its location in a region rich in avian life. During the Middle Ages, Aveiro became a significant port and a center for cod fishing and trade. The city’s canals and waterways were developed during this period, earning it the nickname "Venice of Portugal." In the 16th century, Aveiro became a royal city under King João I, and its Art Nouveau architecture flourished in the late 19th and early 20th centuries, leaving a lasting mark on the city’s skyline. Today, Aveiro’s historic and cultural heritage continues to attract visitors from around the world.

Costa Nova has a rich history tied to the fishing and maritime traditions of the Aveiro region. The village’s colorful striped houses (*palheiros*) were originally built as storage spaces for fishing gear and later converted into homes for local fishermen and their families. The stripes were traditionally painted in bright colors to make the huts easily visible from the sea, helping fishermen locate their homes after long days at sea. Over time, the *palheiros* became a symbol of Costa Nova’s unique identity and charm. The village’s location along the Ria de Aveiro lagoon system also made it an important center for fishing, salt production, and trade, contributing to its cultural and economic heritage.
