In 1711, king Dom João V vowed that if he was blessed with a son, he would construct a convent in Mafra. When a son was born in 1714, Dom João V spared no expense to fulfil his promise. By one count, the building has 880 rooms and 4,500 doors and windows. The convent includes a magnificent palace for the royal family and a basilica made of the purest marble, with intricate altars lavishly decorated with gold leaf.
To top it all, the king commissioned a 200-ton carillon. According to legend, when the craftsmen quoted the price of the carillon, they remarked that the cost seemed too dear for a small country like Portugal. Offended, the king replied: “I didn’t realize the bells were so cheap! I would like two sets.” And so, two sets were made. Nicholas Levach made 57 bells for the North tower in Liége. Willem Witlockx made 49 bells for the South tower in Antwerp.
The convent has many other bells: liturgical bells used in religious ceremonies, lecture bells that signaled the beginning and end of study periods, agony bells that rang when a monk was dying, refectory bells that reminded monks of their meal times, and the codfish bell that sounded in days when people should abstain from eating meat.
The carillon and some of the other bells were used to mark the passage of time with minuets and other compositions. In a world where musical sounds were rare, the bells of Mafra filled the village with harmony and grace.
