Over the years, several monarchs supported this Monastery, with successive donations, making it one of the most important in the country. However, in the 15th century and part of the 16th century, the Monastery of Santa Maria de Bouro entered a phase of decline, reducing the number of monks. After these turbulent times, at the end of the 16th century, the monastery began to recover its autonomy and prosperity. There were several reforms that helped restore the Cistercian monasteries to their former glory.
Currently, part of the convent has been adapted into a Pousada de Portugal, where the conservation of the original design and the severity of the old Monastery make it a national reference. Designed by architect Souto Moura, this Pousada de Portugal stands out for its distinctive and innovative concept, inspired by times long gone by.
Knowing about the great miracles that Senhora do Monte performed, many people came to venerate her, thus creating the Hermitage. The Hermitage grew to such an extent that the rudimentary dwellings were replaced by small houses, and there was even a central convent. The church was also enlarged and furnished with fine ornaments.
After the death of the Abbot Hermit, he was succeeded by Paio Amado and D. Nuno. King D. Afonso Henriques ordered the construction of a new monastery in a more pleasant location, that is, in Bouro and in 1148, he granted it a charter of Couto, which was renewed in 1162.
This new monastery adopted the Cistercian Order. Despite having prospered quickly thanks to royal support, its location, and the activity of the friars, the monastery began to decline from the 15th century onwards.
In 1834, with the extinction of male religious orders, the monastery was abandoned and later sold at public auction to private individuals.
