Fortified church of Leça do Balio
The Monastery of Leça do Balio, which houses the fortified church of Santa Maria de Leça do Balio, was probably founded in the 10th century at the border of the Asturian Kingdom in the context of the Reconquista. In possession of the Order of Malta from the 12th century, the monastery received further enlargements and renovations that gave it defensive features in Romanesque style, the most striking element of which was the construction of the 28 meters high tower provided at the top with machicolations and arrowslits.
