Igreja matriz de Fronteira

Igreja Matriz de Fronteira (the Parish Church of Nossa Senhora da Atalaia) is the principal church of the town of Fronteira, in Portugal's Alentejo region and Portalegre District. It dates from the late sixteenth century and still anchors the town centre. Its two white towers with blue accents make it easy to spot from a distance.

What is the history of the church?

Construction was ordered by a royal charter of 1571, issued during the reign of Sebastian I. Work was completed in 1599 under the supervision of the knight-commander Lucas de Portugal. Over the following centuries the building was enlarged and restored several times, right up to the mid-twentieth century. These campaigns altered its original appearance, although its overall character remains clear.

Why is it called Nossa Senhora da Atalaia?

The church is dedicated to Our Lady of the Watchtower. According to tradition, the name refers to an old lookout structure with two arches that still stood in front of the church in 1791 ("atalaia" is the Portuguese word for a watchtower). The current statue of the patron saint has stood on its altar since 1780, donated by the commander José de Portugal.

What architectural style does it show?

The building blends Renaissance design with a transition toward Mannerism, with Baroque touches in the decoration. The facade is framed by two square bell towers painted white and blue. Their corners are emphasised with dressed stone, and the tops are crowned with small bird figures. The contrast of pale walls and stone detailing gives the church a light, cheerful look typical of Alentejo towns.

What can you see inside?

The interior has three vaulted naves of five bays, all of equal height, which creates a spacious, hall-like feel. Highlights include:

• sixteenth-century Mannerist paintings,
• an altarpiece of Estremoz marble, from a region famous for quarrying that stone,
• a marble high altar and a marble altar of the Sacred Heart,
• the altar of Saint Louis, decorated with gilded woodcarving,
• polychrome wooden statues from the seventeenth and eighteenth centuries, including Our Lady of the Watchtower, Our Lady of the Conception, Saint Michael and Saint Anthony.

How to plan a visit

The church stands in the centre of Fronteira, so it is easy to combine with a stroll around the town. A visit usually takes thirty to sixty minutes. Remember that this is a working parish church: access may be limited during services, and modest dress and quiet are expected. It is worth checking opening hours beforehand with the town hall or the local tourist information point.
