The Church was classified as “valor concelhio” [municipal patrimony] in 1975, having received modification works in the pavement of the surrounding churchyard, including the spread of gravel to accommodate the quartered screed finishing.
However, its classification changed to National Monument, thus suspending the intervention and replacing the original pavement. The coating of the nave was varnished in 1977 by the parish.
In 1991, the exterior doors of the Church are replaced and, two years later, the parish engages in the restoration of the main altar.
The most significant intervention took place in 2004, envisaging the general preservation of the property, and included interventions involving the roofing, the outer spans, the ceiling of the nave, the batters of the two lateral chapels, the chapel of the Baptistery, the execution of three interior doors with iron railing, the heads, the recommissioning of the bells and recasting of the electrical wiring of the Church.
On the roof of the chancel the existing tiles were removed, the structure, with the replacement of decaying woodwork, was repaired and reinforced, the crowning of the batters was repaired and regulated in the joints of the roofing structure, with the occasional replacement of granite masonry and jointwork with lime mortar and sand at 1:3, among other interventions, namely the curative and preventive disinfection of all woodwork against xylophagous insects and fungi. Similar interventions were performed on the roofing of the nave and the sacristy.
In the exterior spans, we proceeded to the removal of the paint coating on doors and windows. In the former, the woodwork was repaired and those that were rotting or somehow damaged were replaced with other identical to the original, the casings were adjusted and reinforced, before proceeding to the general polishing of the woodwork, which also happened in the case of the windows. For the finishing, matt-glossed oil paint was used.
The glass was removed from the rosette and replaced by other simple and colourless.
The varnish of the wood work in the ceiling and coves of the nave were removed before the preparation and trowelling of the surfaces with liquefied beeswax, after the uniformisation of the colour of the reintegrated areas by using aniline diluted in water.
For the interior batters of the two side chapels, the joints were carefully cleaned by removing all the cement mortar in order to reclose them with mortar of lime and sand at 1:3, to which a water repellent product was added.
The finishing of the surfaces was plastered with lime painting and fixer. In the intervention for the preservation of the baptism side chapel a very similar process was used, to which the application of a floor pavement with the same colour and grain of the stone was applied, sitting on regularization screed including the joints, general review of the iron railing in the chapel, including the stripping of any existing paint, the application of a sub-layer of paint and repaint with plumbago, the removal of the varnish on the wooden cover of the baptismal font and the preparation of surfaces for wooden finishing with liquefied beeswax waxing, applied with trowel.
The restoration work also implied the removal of the existing wooden doors in the access to the pulpit, the choir and the bell tower, replaced by iron gates with plumbago painted finishing.
Finally, we proceeded to the intervention for the preservation and restoration of the functioning of the bells, including the stripping of the paint from woodwork and metal parts, the repair of the woodwork of the of the bell heads and the replacement of those who were in a state of deterioration by other identical to the original, filling of cracks and gaps with inlaid woodwork identical and / or with the use of a mass composed of sawdust and carpenter glue, general polishing of all woodwork, application of a polishing machine in two crossed stages, oil paint finishing in the colour similar to the spans, of matt gloss, and the painting of metal elements with lackluster black oil paint.
