Monte Gralheiro
It is a group of three different granite monoliths that are positioned harmoniously. The highest is Mount Gralheiro (known as Lapa da Fazenda), a natural viewpoint par excellence for observing and contemplating the parish and the Talhadas mountain range and part of the Caramulo mountain range.
On clear days, you can also see the horizon of the lagoon coast (Ria de Aveiro).
With a height of over 20 metres, compared to the 7 metre oval monolith (Azeiteiro) near the Monte Gralheiro road and the curious inverted cone monolith (Vinagreiro) in the same location, these monoliths are part of Sever do Vouga's natural heritage.
It should be noted that monoliths are very common in the Talhadas mountain range, originating in the huge granite outcrops characteristic of the region, and can be classified into larger, intermediate and detailed forms. The "Talhadas Stones", which gave rise to the parish's name, are an excellent example of intermediate forms, which also include the Musgo monolith, near Silveira.
