Olho Marinho: Springs, Heritage and Festivals

Olho Marinho brings together a landscape of springs, religious heritage and recurring festivals. For travelers who choose a destination based on its cultural and natural features, there are several specific points of interest: the Olhos d'Água springs, the group of caves on the Planalto das Cesaredas, historic places of worship and events with fixed dates. This guide can help you prioritize your interests for your stay before looking for a hotel.

Springs and Trails

The Olhos d'Água springs lie in the center of Olho Marinho. They emerge from the rock, have a constant temperature of 21 degrees Celsius and form the source of the Rio Olho Marinho. The combination of a consistent temperature and the river's source gives the springs two distinct points of interest: a physical feature and their hydrological role. According to local tradition, a second group of springs has been known as Olho da Rainha since the 14th century; this date, too, is part of local tradition.

Largo da Fonte is a place of rare natural beauty. The Caminhos Antigos project in Olho Marinho and on the Planalto das Cesaredas includes restoring old paths, creating viewpoints, and marking hiking and cycling routes. The project therefore covers both features such as old paths and viewpoints and practical guidance for hiking and cycling.

Heritage and Religious History

In 1866, Casa da Moura was classified as the “main cave” in the group of caves and karst shafts on the Planalto das Cesaredas. This designation places it within the cave group and also gives the local landscape a historical point of reference.

The Igreja do Imaculado Coração de Maria, also known as the Igreja em Honra do Imaculado Coração de Maria, was inaugurated in August 1856. Despite later maintenance and restoration, it retains its original architectural layout. For those interested in religious architecture, both its inauguration and its preserved original form are noteworthy.

The Ermida de Santa Iria was built in the 15th century and is considered probably the second-oldest place of worship built by the people of Olho Marinho. Until 1856, it was the community’s main place of worship. That year thus marks the end of its central religious role; in August of the same year, the Igreja do Imaculado Coração de Maria was also inaugurated.

Festivals and Dates

The Festa do Imaculado Coração de Maria takes place every year in the second half of August and includes a procession through Olho Marinho. Another fixed date is June 13: the Feira de Santo António is held every year on this day and features an extensive entertainment program. On August 15, the Festival de Folclore brings together folk groups from different parts of Portugal.

The dates vary: specific days are given for the fair and the folk festival, while the Festa takes place in the second half of August. Their focus also differs—from the procession and entertainment program to the gathering of folk groups. If you want to plan your stay around a particular festival, check the dates for your intended travel period.
